###### WSU Analysis Seminar: Yufeng Cao

Title:: Maximum flow algorithm for total variation minimization
Abstract: This topic studies the global minimization of total variation energies with an $L^1$ fidelity term using maximum flow algorithm to minimize $s-t$ cut representation of these energies. I will present why the total variation functional can be decomposed into a series of decoupled of problem in binary variables. And how to construct network whose $s-t$ cuts correspond one-to-one to the binary variables for these decoupled problems. Finally how to apply the push flow relabel algorithm to solve the minimize problem.

###### WSU Analysis Seminar: Dr. Matt Duez

Title:: The Leibniz-Clarke debate revisited
Abstract: It turns out that the tools of differential geometry are being heavily used by philosophers investigating the ontological status of spacetime, i.e. whether spacetime is a real thing or just a useful abstraction and which quantities of motion have absolute significance. I will review some interesting milestones in this ongoing discussion, such as dynamics in Machian space, Cartan's nonrelativistic curved-spacetime theory of Newtonian gravity, and Einstein's hole argument (that almost convinced him that general covariance is a bad thing).

###### 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:Joseph H. Nakao

Abstract: Water-wave equations are highly nonlinear in nature and often require methods that produce approximate solutions, such as asymptotic expansions. Given a non-constant bathymetry, I attempt to reconstruct the surface elevation and pressure.

###### 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.

###### WSU Analysis Seminar - Speaker: Yunfeng Hu

Yunfeng Hu will speak on, "Concentration of Measure"
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.

###### 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.

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.

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.

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.
