This meeting will take place at the Pacic Institute for the Mathematical Sciences (PIMS) on the campus of the University of British Columbia in Van couver on Saturday morning, August 5, 2017, from 9AM to noon. The purpose of this meeting is to...

Hamilton-Jacobi-Bellman (HJB) equations are nonlinear partial differential equation that arise as optimality conditions of stochastic control problems. HJB equations often possess a variety of difficulties, e.g., discontinuous coefficients, vanishing...

In this talk we consider a class of games with continuum of players where equilibrium can be obtained by the minimization of a certain functional related to optimal transport. We then use the powerful entropic regularization technique to approximate...

Optimization problems with sparsity enhancing norms have helped enable the tremendous success of computational compressed sensing techniques in the past decade, where the goal is to recover a signal from a small number of measurements. In this...

In quantum mechanics d-partite systems are presented by d-mode tensors.Unentangled states are rank one tensors. Entangled states can be characterized their rank > 1, their spectral norm 1 or their nuclear norm > 1. In this talk I will discuss...

The impact of the annual influenza epidemic is still large; 36,000 deaths in the US each year. Elderly are in particular vulnerable for side effects of an infection. Therefore they need to be protected against getting infected, however, vaccines are...

Last time we have seen that the spectrum for commutative K-theory is equivalent to the ku-group ring of BU(1). In this second talk I will show how this induces a splitting of the space BcomU as a product of all the stages in the Whitehead tower for...

Fields Medal winner, Martin Hairer will survey some of the mathematical objects arising naturally in probability theory, as well as some of their surprising properties. In particular, he will demonstrate how one of these objects was involved in the...

Abstract: The study of spaces of homomorphisms from a discrete group to a compact Lie group has led to the definition of a new cohomology theory, called commutative K-theory. This theory, which was first introduced by Adem and Gomez, is a refinement...
