Title: On almost all matroids
Speaker: | Peter Nelson |
Affiliation: | University of Waterloo |
Room: | MC 5417 |
Abstract: I will discuss a recent paper of Pendavingh and Van der Pol that resolved several natural, long-standing conjectures about the properties of almost all matroids. Namely, for some m that is polylogarithmic in n, almost all matroids on n elements are m-connected, have girth at least m, and have the rank-m self-dual uniform matroid as a minor.
Title: Douglas-Rachford feasibility methods for matrix completion problems
Speaker: | Jonathan Borwein |
Affiliation: | University of Waterloo |
Room: | MC 5501 |
Abstract: Many successful non-convex applications of the Douglas-Rachford reflection method for finding a point in the intersection of two sets can be viewed as the reconstruction of a matrix, with known properties, from a subset of its entries.
