University of British Columbia
Statistical and probabilistic methods are promising approaches to solving inverse problems – the process of recovering unknown parameters from indirect measurements. Of these, the Bayesian methods provide a principled approach to incorporating our...

Lethbridge Number Theory and Combinatorics Seminar: Lee Troupe
October 16, 2017
University of Lethbridge
In the late 1930s, Paul Erdos attended a seminar at Cornell University given by Mark Kac, who suspected that divisibility by primes satisfies a certain "statistical independence" condition. If this were true, the central limit theorem could be used...

Fall 2017 UBC-SFU Joint Statistics Seminar
October 14, 2017
Simon Fraser University
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...

PIMS- SFU CSC Seminar: Ludvig af Klinteberg
October 13, 2017
Simon Fraser University
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...

Math Biology Seminar: Frédéric Paquin-Lefebvre
October 11, 2017
University of British Columbia
Two models involving bulk diffusion coupled to nonlinear reactions localized to the boundary are presented. For each of them, a combination of analytical and numerical methods exhibits a variety of exotic dynamics including in-phase and anti-phase...

Probability Seminar: Gordon Slade
October 11, 2017
University of British Columbia
The subject of critical phenomena in statistical mechanics is a rich source of interesting and difficult mathematical problems that touch on combinatorics, probability, and mathematical physics. Self-avoiding walks and lattice spin systems provide...

Discrete Math Seminar: Samantha Dahlberg
October 10, 2017
University of British Columbia
Richard Stanley introduced the chromatic symmetric function X_G of a simple graph G, which is the sum of all possible proper colorings with colors {1,2,3,...} coded as monomials in commuting variables. These formal power series are symmetric...

Diff. Geom, Math. Phys., PDE Seminar: Yong Liu
October 10, 2017
University of British Columbia
We prove that the lump solution of the classical KP-I equation is nondegenerate and its Morex index is one. As a consequence, it is orbital stable.

UBC Math Department Colloquium: Craig Westerland
October 6, 2017
University of British Columbia
The inverse Galois problem asks whether every finite group occurs as the Galois group of an extension of the rational numbers. In 2002, Malle made this existential question more numerical, by conjecturing an asymptotic formula on the growth of the...

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...
