Number Theory and Combinatorics
Number theory research in our department predominantly uses an Analytic perspective, with an emphasis on modular forms and Lfunctions. There is also overlap with work in combinatorial number theory, including multidimensional recurrence relations. Much of the combinatorial research we carry out is related to graph theory and discrete geometry, with particular emphasis on problems in spectral graph theory, random walks on graphs, random graph models, and related enumerative constructions. This research group also incorporates the analysis of discrete algorithms, including probabilistic approaches.
