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...

We study the propagation of chaos for the N-particle chemotaxis system subject to the Brownian diffusion. More precisely, we present a probabilistic proof of the distance between the exact microscopic and the approximate mean-field dynamics, which...

The rapid increase of fentanyl and fentanyl analogues in British Columbia has led to a public health emergency being declared and a rapid increase in overdoses and overdose-related deaths in the province. Numerous interventions have been proposed in...

The idea of this event is to offer graduate students in Statistics and Actuarial Science with an opportunity to attend a seminar with accessible talks providing them an introduction to active areas of research in the field. For three students from...

The approach of Nigel Gay for estimating the coverage of multivalent vaccine (MMR = measles, mumps, rubella) out antibody prevalence data leads to a polynomial system of equations of degree six describing a generically 2:1 covering of the 7...

Borcherds won the Fields medal in 1998 for his proof of the Monstrous Moonshine Conjecture. Loosely speaking, the conjecture asserts that the representation theory of the Monster, the largest sporadic finite simple group, is dictated by the Fourier...

My talk will be on boundary integral methods, which is a class of powerful methods for solving certain elliptic PDEs, such as the Laplace, Helmholtz and Stokes equations. These methods require efficient and accurate evaluation of singular and nearly...

We introduce an efficient algorithm, called partition of unity extension or PUX, to construct an extension of desired regularity of a function given on a complex multiply connected domain in $2D$.Function extension plays a fundamental role in...
