The drainage of meltwater under glaciers affects the motion of the glacier as a whole. High water pressure weakens ice-bed contacts and allows more rapid slip at the interface. A glacier flow model therefore requires a component that predicts water...

This is a working seminar in Topology. We will start a series of talk about model categories.

This is a report on my joint work with Prakash Belkale and Nicolas Ressayre. We prove a generalization of Fulton’s conjecture which relates intersection theory on an arbitrary flag variety to invariant theory.

In light of the rapid recent retreat of Arctic sea ice, a number of studies have discussed the possibility of a critical threshold beyond which the ice-albedo feedback causes the ice cover to melt away in an irreversible process. The focus has...

Abstract The Mayer expansion is a power series expansion that has a central place in statistical mechanics. It is also full of combinatorial miracles that relate it to graphs, forests and branched polymers. I will discuss the background, the results...

An activity of the PIMS Collaborative Research Group in L-functions and Number Theory

AbstractWe summarize the current meager state of knowledge concerning how often values of polynomials have only small prime factors (that is, the values are "friable" or "smooth"). We also present some evidence, in the form of a theorem conditional...
