This talk will be in two parts. The first will give an idea of what computations are possible with L-functions, and what uses they have. The second part will give more explicit details for some of the work being done under a Focused Research Group...

A Diophantine m-tuple is a set of positive integers such that the product of any two distinct elements, increased by 1, is a perfect square. We will derive an asymptotic formula which counts the number of Diophantine quadruples with elements bounded...

I will consider a random walk in random environment obtained by putting iid bond weights $\mu_e$ on the bonds in the lattice $Z^d$.(Here $d\ge 3$). We assume $\mu_e \ge 1$, but have heavy tails: $P(\mu_e > t) \sim t^{-\alpha}$ with $\alpha \in (0,1)$...

We consider the problem of colouring the planar map given by the Voronoi tessellation corresponding to a Poisson process in R^2. We seek deterministic colouring rules that are independent of the coordinate system (formally: isometry covariant and are...

We present and investigate models for solid tumor growth that incorporate features of the tumor microenvironment including tumor-induced angiogenesis. Using analysis and nonlinear numerical simulations, we explore the effects of the interaction...

This event is a one day conference organized exclusively for and by graduate students. The intent is to give students an opportunity to network and present their research in a relaxed and non-stressful environment -- particularly students who may not...

Time & Date: 12:00 p.m., Friday, January 23, 2009 Subject: ``Almost commuting elements in Lie Groups'' Location: WMAX 216 Abstract: In this non technical talk I will show how one can use the space of almost commuting elements in a compact Lie group G...

This talk is dedicated to the memory of Bernard Perron, who recently passed away. We collaborated on work involving automorphisms of a free group: he showed me how to understand the induced automorphisms on the lower central series quotients, using...

Statistical mechanics is the branch of physics that seeks to explain the properties of matter that emerge from microscopic scale interactions. Probabilistic models such as percolation help describe various physical phenomena. The models are generally...
