Abstract: During reproduction, viruses manufacture products that diffuse within the host cell. Because a virus does not have exclusive access to its own gene products, coinfection of multiple viruses allows for strategies of cooperation and defection...

Abstract: In this talk we will present a new upper bound of $s_r(K_t) = O(t^5r^{5/2})$ on the Ramsey parameter $s_r(K_t)$ introduced by Burr, Erd\H{o}s and Lov\'{a}sz in 1976, which is defined as the smallest minimum degree of a graph $G$ such that...

Hosted for a Fourth year by PIMS, Diversity in Mathematics is part of a multi-year, multi-level program geared towards promoting diversity and inclusivity in STEM. The highlights of the week program include: An interactive math day camp for high...

In this talk, I will discuss random walks on Gromov hyperbolic spaces. Due to the hyperbolicity of the spaces, random walks exhibit behaviors that differ from the classic (Euclidean) ones. These behaviors include the escape to infinity, central limit...

Abstract: The principal function of the nucleus is to facilitate storage, retrieval, and maintenance of the genetic information encoded into DNA and RNA sequences. A unique feature of nucleoplasm—the fluid of the nucleus—is that it contains chromatin...

Abstract: A k-list-assignment for a graph G is a function L from V(G) to the set of subsets of {1,…,k}. The list-k-colouring problem asks, given G and a k-list-assignment L, is there a colouring f of G with f(v) in L(v) for all v in V(G)? This...

Abstract: In 1964, Kemperman proved the following continuous nonabelian counterpart of the Cauchy-Davenport theorem: If G is a connected unimodular locally compact group with a left (and hence right) Haar measure \mu, A, B \subseteq G are nonempty...

Here I give two tiny talks on some of my research from the past couple years. In the first half of the talk I re-examine some popular heuristics for epidemic "time of spread" through the world airline network, and use hitting times and branching...

Abstract: From a group action on a space, define a variant of the configuration space by insisting that no two points inhabit the same orbit. When the action is almost free, this "orbit configuration space" is the complement of an arrangement of...

The purpose of the conference is to bring together experts from across automorphic forms,representation theory, and arithmetic connected to the theory of theta series and the theta correspondence in order to survey the most recent developments and to...
