###### WSU Analysis Seminar

Zach Hilliard will give a talk titled, "Generalized Functions and their Derivatives."
Abstract: Standard functions are very nice and conceptually concrete. However, although many functions are integrable, by comparison not many are differentiable this can be limiting (for example when solving differential equations). We will take an introductory look at objects called generalized functions (or distributions, depending on the author) and how we can define derivatives of these objects in a manner so that in this context every function which can be integrated can also be differentiated. Moreover, for functions which are classically differentiable, these notions coincide. This should be accessible for anyone who is comfortable with real analysis.

###### WSU Analysis Seminar

Zach Hilliard will give a talk titled, "The Cahn-Hilliard equation."
Abstract: I am interested in a generalized version of the Cahn-Hilliard equation, which is a nonlinear parabolic type PDE. As an aid to understanding this generalized version, I use Galerkin approximation to show existence and uniqueness of a weak solution to the standard equation, provided a certain intermediate lemma is true. This method of proof also gives some insight to the finite element method, which is used to numerically approximate solutions to many PDEs.

Abstract: This seminar will discuss medical imaging, which is a very hot topics in image analysis. The segmentation of a liver tumor is an interesting and challenging task. Recent research in this field highlights the potential of graph based methods, which have generated a big interest in imaging analysis. Graph theory is the framework for this thesis to do some further study. We focus on both theoretical and practical. On the theoretical side, new models were studied and a lot of new points were generated based on our data. The big point is the $\alpha$ method we developed, which can tell us a lot of information. Images were taken over a period of time during which a medical dye was distributed in the patient's liver via the blood vessels, which caused the intensity of the tissues in the image to change from their normal state, with tumor and vessel tissues changing the most. Finally, we propose our model to new data, which is big challenging recently. And moving mean was studied based on this purpose.

###### WSU Analysis Seminar

Dr. Matt Duez will give a talk on, "Space without points: the fuzzy sphere for physics students."
Abstract: for over half a century, physicists have speculated that the manifold structure of spacetime breaks down at very small scales, that on these scales spatial coordinates do not commute, and that this noncommutivity may be a key to regularizing field theories, resolving spacetime singularities, quantizing gravity, and other wondrous things. The "fuzzy sphere" is a simple example of how one can build up differential geometry without the usual manifold substructure. Alas, most introductions to noncommutative geometry are written at a level of abstraction that is taxing to the average physicist. Okay, I should say "taxing to this physicist", but I'm sure I'm not the only one. I'd like to give a more "nuts and bolts" account of how to build a description of a world without points.

Abstract: The original traveling salesman problem asks us to compute the shortest path that goes through a finite number of points in the plane. If instead of a finite number of points, we have a continuum, when can we cover such a continuum with a connected curve of finite length? To solve this problem, Peter Jones introduced the Beta numbers; they are used to quantitatively answer geometric analogues to some classical questions coming from Littlewood-Paley theory.

###### WSU Analysis Seminar: Dave Field

Title: Stereological Characterization of Grain Boundaries and Triple Junctions in Polycrystals
Abstract: Given the increasing awareness of their influence on material properties, grain boundaries and triple junctions in polycrystalline materials have become a focal point of substantial research. Despite increasing interest, there is a deficiency in experimental methods for fully characterizing these junctions on a large scale. This work provides the necessary foundation for experimentally generating fully characterized grain boundary and triple junction distributions from a single section plane, or from a series of planes. Experimental difficulty lies in collecting sufficient information by conventional techniques to enable determination of statistically reliable distributions. Various analytical and experimental approaches are described and various measurements are shown.

###### Porous Media Seminar - Milena Rangelov

Doctoral candidate, Milena Rangelov, from Civil and Environment Engineering, will speak on "Optimization of Water Vapor Diffusivity Models of Mortar". Abstract: Cementitious composites exhibit shrinkage due to the loss of moisture through cement hydration (autogenous shrinkage) and drying (drying shrinkage). When restrained, shrinkage may cause cracking, which creates a premature failure and loss of serviceability of cement-based infrastructure. Reliable characterization of shrinkage demands the appropriate establishment of water vapor diffusivity, since drying of cementitious composites is typically described as a diffusion process. This talk presents a combined experimental and modeling study focused on characterization of water vapor diffusivity of 7 mortar mixtures using the inverse modeling technique. Implemented novel calibration methodology provided an enhanced understanding of the existing vapor diffusivity models for cementitious composites.
The seminar will take place at 4:10pm in PACCAR 202.

Title: L-Functions Associated to Modular Forms and the Non-Vanishing of their Derivatives at the Central Point
Abstract: Arithmetic objects over the rationals, such as number fields or elliptic curves, often have an associated complex-valued function called an L-function. These functions can be studied analytically to derive useful information about the object. In this talk I will introduce L-functions, and give examples of different types as well as how they are used. Then we will concentrate on families of L-functions associated to modular forms, and an outline of the proof that a positive proportion of these functions are non-vanishing at the central point of s=1/2.

Dr. Markus Flury, from the Department of Crop and Soil Sciences, will give a seminar on, "The Role of Air-Water Interfaces in Colloid Transport in Porous Media."
Abstract: Colloids can enhance the transport of otherwise immobile contaminants in soils and sediments. Colloids can themselves be contaminants, such as bacteria or viruses. In the vadose zone, colloid transport is usually less pronounced than in groundwater, mainly because the flow pathways are more restrictive and colloids get strained by water films or attach to air-water interfaces. However, air-water interfaces can also lead to colloid mobilization and enhanced transport. This talk will discuss the importance of the air-water interface in colloid transport and highlight how colloids interact with the air-water interface.
The seminar will take place at 4:10pm in PACCAR 202.

###### Combinatorics, Linear Algebra, and Number Theory Seminar - Come enjoy a film!

Come watch the film, "Counting from infinity - Yitang Zhang and the twin prime conjecture."
In April 2013, a lecturer at the University of New Hampshire submitted a paper to the Annals of Mathematics. Within weeks word spread-- a little-known mathematician, with no permanent job, working in complete isolation had made an important breakthrough towards solving the Twin Prime Conjecture. Yitang Zhang's techniques for bounding the gaps between primes soon led to rapid progress by the Polymath Group, and a further innovation by James Maynard. The film is a study of Zhang's rise from obscurity and a disadvantaged youth to mathematical celebrity. The story of quiet perseverance amidst adversity, and Zhang's preference for thinking and working in solitude, is interwoven with a history of the Twin Prime Conjecture as told by several mathematicians, many of whom have wrestled with this enormously challenging problem in Number Theory-- Daniel Goldston, Kannan Soundararajan, Andrew Granville, Peter Sarnak, Enrico Bombieri, James Maynard, Nicholas Katz, David Eisenbud, Ken Ribet, and Terry Tao.

###### Colloquium:Dr. Matthew Hudelson

Abstract: We examine some results that center around prime divisors of binomial coefficients, leading off with Lucas’ theorem—a result that greatly facilitates computing (𝑛/k) modulo p. This result has a striking visual connection with the Sierpinski triangle when p=2. As a follow up from Lucas’ theorem, we will examine various quick results concerning what prime powers pk divide binomial coefficients. The second result we will examine is Bertrand’s postulate: For any integer n ≥ 1, there is always a prime number in [n, 2n]. We will present a version of Erdős’ proof of Bertrand’s postulate that uses remarkably crude estimates concerning primes that divide the central binomial coefficient (2𝑛/𝑛). Refreshments served during the event!
The colloqium will meet from 4:10pm to 5:00pm in Neill 5W, and refreshments will be served during the event. See you there!

###### WSU Analysis Seminar:Laramie Paxton

Title: Rademacher Functions and L^p Norms
Abstract: Building on the previous discussions of Rademacher Functions (RF), we will explore a fundamental result in analysis known as Khintchine's Inequality, which states that for a function f: R^n-->R that can be expanded with RF, all its L^p norms (p is less than infinity) are comparable. The proof will demonstrate many key techniques used in analysis; for example, *creative* use of Holder's Inequality; proving a finite result and then passing to the limit; and a normalizing assumption, which then uses a scaling argument for the general case. We will also make use of orthonormality, mutual independence, and a distributional inequality, with some closing remarks on the best possible constants in Khintchine's Inequality.

###### Colloquium: Alina Bucur (UC San Diego)
Alina Bucur, from UC San Diego, will present a colloquium on "Arithmetic statistics: points on curves over finite fields."
Abstract: A curve is a one dimensional space cut out by polynomial equations. In particular, one can consider curves over finite fields, which means the polynomial equations should have coefficients in some finite field and that points on the curve are given by values of the variables in the finite field that satisfy the given polynomials. A basic question is how many points such a curve has, and fora family of curves one can study the distribution of this statistic. We will give concrete examples of families in which this distribution is known or predicted, and give a sense of the different kinds of mathematics that are used to study different families.
The colloquim will meet in Neill 5W from 4:10pm to 5:00pm.

###### Introducing a new book by Dr. Alex Khapalov

Mobile point sensors and actuators in the controllability theory of partial differential equations, published by Springer.
This book presents a concise study of controllability theory of partial differential equations when they are equipped with actuators and/or sensors that are finite dimensional at every moment of time. Based on the author’s extensive research in the area of controllability theory, this monograph specifically focuses on the issues of controllability, observability, and stabilizability for parabolic and hyperbolic partial differential equations. The topics in this book also cover related applied questions such as the problem of localization of unknown pollution sources based on information obtained from point sensors that arise in environmental monitoring. Researchers and graduate students interested in controllability theory of partial differential equations and its applications will find this book to be an invaluable resource to their studies.

Abstract: "in probability theory, the mean is an important value for a random variable. Chebshev's inequality says that with "high chance", the values for a random variable will be "very close" to its mean. In this talk, I will generalize this idea to R^n when the probability measure is Gaussian. I will prove R^n is more or less like a sphere with radius sqrt{n} and its k dimensional subspace will be like a sphere with radius sqrt{k}. Then I will show that for any Lipschitz function $f$ defined on Boolean cube, $f$ is very close to its mean. And in the end, I will present an "isoperimetric inequality" result in Boolean cube". The WSU Analysis Seminar will meet at 4:10pm in Neill 5W.

###### Analysis Seminar: "Fourier expansion of Boolean functions f: F_2^n \to F_2"

Vladyslav Oles will be the speaker.
*Abstract*: It's meant to be an introduction to the area which looks like a bridge between Boolean logic and harmonic analysis. We will go through the alternative notation of Boolean domain and introduce the idea of Fourier expansion for Boolean functions coming from interpolating 2^n sampled "data points". We'll talk about the vector space where Boolean functions live and we will get to know logical parity functions along the way, who will reveal themselves as orthonormal basis for this space. Also, I promise that it is much easier to understand than it might sound here in the abstract. The seminar will be held in Neill 5W from 4:10pm to 5:00pm.

###### Analysis Seminar: "Constant Mean Curvature for Volume-constrained Perimeter Minimizer"
Laramie Paxton will discuss the proof for the theorem implied in the title related concerning variations of sets E of finite perimeter in R^n restricted to open sets A. He will show that for a compactly supported C-infinity vector field T: A-->R^n that produces a zero first order volume variation of E, then the condition of being a volume-constrained minimizer implies that T produces a zero first order perimeter variation of E. By then constructing such a T in a special way and using a partition of unity on a finite cover of balls, the result is obtained.
The seminar will be held in Neill 5W from 4:10pm to 5:00pm.

###### Analysis Seminar: Introduction to Numerical Relativity
Matt Duez will speak on an "Introduction to Numerical Relativity."
Abstract: Systems involving strongly curved spacetimes, especially the vicinities of compact objects (black holes and neutron stars), must be modeled using the general theory of relativity. Except in special, high-symmetry cases, this requires numerical simulation. The four-dimensional theory must be "split" into a three-dimensional system evolved through time; coordinate choices must be made and their effects separated from physically meaningful dynamics; physical singularities must be treated in a numerically stable way. If we can do this, we can simulate the merger of compact binary systems and make predictions about gravitational waves and gamma ray bursts.
The seminar will take place from 4:10pm to 5:00pm in Neill 5W.

A reception will immediately follow in CUE 518. Abstract: Everybody has opinions about mathematics and how it is learned. What are some of the myths about how mathematics is learned? How do people understand-and misunderstand mathematics? What are some of the theories that explain how mathematics is learned? This session will discuss some of the research in mathematics education that has uncovered ways that people understand and misunderstand mathematics. Click here for a pdf flier.

They are using the simulation, detailed in a new paper in Royal Society Open Science, to determine how drought, warmer weather, more frequent wildfires and other climate-related changes will affect forests across North America. Mar 2 ###### Seminar: "A probalistic characterization of negative definite functions" Presented by Frank Gao. 4:10pm in Neill 5W. *Abstract*: Negative definite functions have many applications in potential theory, statistics, and the theory of probability. For example, it is closely related to L\'{e}vy processes. In this talk I will provide a probabilistic characterization of negative definite functions; namely, a continuous tempered distribution f on R^n is negative definite if and only if it satisfies the inequality E f(X-Y) <=E f(X+Y) for all i.i.d. random vectors X and Y in R^n. Without the assumption of slowly growing of tempered distributions, it is shown that E e^{|X-Y|}<= E e^{|X+Y|} for all i.i.d. random variables in R, while the function e^{|x|} is not negative definite. Feb 24 ###### Seminar: "Metric Entropy and Approximate Convexity" This will be a presentation by James Cockreham of his and Frank Gao's work. 4:10pm in Neill 5W. Feb 23 ###### Seminar: "Mathematical Modeling and Computational Methods for the Tumor Microenvironment" Presented by Dr. Bob Dillon at 4:10pm in Webster B8. ###### Welcome Sotiris Xantheas The department is pleased to announce that Sotiris Xantheas has been hired as an adjunct faculty member. He was born and raised in Athens, Greece, and obtained a Diploma in Chemical Engineering from the Technical University of Athens and a PhD in Chemistry from Iowa State University in Ames, Iowa. After a two year post-doctoral fellowship at Pacific Northwest National Laboratory (PNNL) he became a staff member and is now a Laboratory Fellow. His research is concerned with the mathematical modeling of the interaction between atoms, molecules and ions using quantum mechanical principles. He is particularly interested in the properties of hydrogen bonds, the interactions responsible for holding together water molecules in clusters, liquid water and ice. He uses supercomputers to evaluate properties of these model systems to ultimately understand the macroscopic properties of water and aqueous solutions. Outside of work, Sotiris enjoys playing soccer, volleyball and tennis. He is looking forward to work with WSU students and faculty on joint projects. ###### Welcome Jingyang Zhang The department is pleased to announce that Jingyang Zhang has been hired as an adjunct faculty member. Born and raised in China, Jingyang obtained her BS in applied mathematics from Peking University, China. She then obtained a PhD in biostatistics at the University of Iowa, and moved to Seattle in 2012 for post doc training at the Fred Hutchinson Cancer Research Center where she currently holds a position as a faculty biostatistician. Her research focuses on statistical modeling with various types of applications in medical research, especially the HIV prevention clinical trials. She works closely with epidemiologists and clinicians on large scale clinical trials. Outside of work, Jingyang enjoys her athletic lifestyle very much. She is an avid runner and an enthusiastic outdoor explorer. As an adjunct faculty member, she eagerly looks forward to working with WSU students. ###### Welcome Dr. Lynn Schreyer The department is pleased to announce the hire of Dr. Lynn Schreyer. Lynn came to us in January from the University of Colorado Denver Department of Mathematical and Statistical Sciences and is delighted to become a Cougar! She has a BS and MS in Mechanical Engineering, an MS and PhD in Math, and did a post doc in Agronomy. Consistent with her education, her research is interdisciplinary - in fact since arriving, WSU has provided the environment for her to pick up work on 3 new projects: modeling gels, concrete, and clays. Her primary research passion is modeling porous materials (think of a solid with pores), and especially porous materials that swell (e.g. gels, concrete, and clays). She uses continuum mechanics and upscaling techniques to formulate the system of partial differential equations, analyzes the system, and then numerically solves it to learn more about the physics. WSU was also kind enough to hire her husband so that they can now live in the same state. Don't be surprised to find her as a spectator at local WSU track events since she used to run track and continues to love the sport.

###### Seminar: "On the Eigenvalues of Matrix Polynomials"

Presented by Thomas Cameron at 4:10pm in Neill 5W.
Abstract: It is well known that the eigenvalues for any
unitary matrix lie on the unit circle. In this talk we will
show that the eigenvalues of any matrix polynomial,
with unitary coefficients, lie inside the annulus
{ complex z such that 0.5 <|z|<2 } The foundations
of this result rely on an operator version of Rouche's
theorem, Pellet's theorem, and the intermediate value
theorem.

###### Memorial Service for Dr. Ed Pate 7pm at the Kimball Funeral Home

Former mathematics faculty member, Dr. Ed Pate, passed away
on January 2, 2016. Dr. Pate had been a faculty member
at WSU for 35 years, ultimately having his tenure home
in the Voiland School’s bioengineering program where he had
a profound impact on the lives of others. Dr. Pate was well
known for his work in computational and quantitative biology,
with applications to Muscle Physiology, Biophysics and
Biomechanics. Recently, with his collaborators at UCSF, he
identified a “Super-Relaxed State” in muscles and was exploring
the implication of this muscle state on health. Dr Pate’s research
was continuously funded by the NIH for many years. Dr. Pate was
a strong advocate for younger researchers, an intelligent
and deep-thinking individual, and an excellent colleague.
He will be missed by his colleagues at WSU and around the nation.
