We introduce an inexact trust-region method for efficiently solving a class of problems in which the objective is the sum of a smooth, nonconvex function and nonsmooth, convex function. Such objectives are pervasive in the literature, with examples...

It has been known since the 80s, thanks to Conrey and Ghosh, that the average of the square of the Riemann zeta function, summed over the extreme points of zeta up to a height $T$, is $\frac{1}{2} (e^2-5) \log T$ as $T \rightarrow \infty$. This...

Selection acts upon genes tied together on chromosomes. This physical association reduces the efficiency of evolution because, in the absence of sex, alleles must rise and fall together in frequency with the genome in which they are found. In this...

The existence and the number of solutions of a system of polynomial equations in n variables over an algebraically closed field is a classical topic in algebraic geometry. Much less is known about the existence of solutions of a system of polynomial...

Live Stream: https://usask-ca.zoom.us/j/95534967223?pwd=0souQ0erQt4B3mWbYTcw19oQgnrJld.1 Details/Abstract: In this talk, I will present a new mathematical formalism of a coupled system of bulk-surface partial differential equations (semilinear...

The framework of mirror symmetry, originally discovered by string theorists, asserts that geometric objects come in "mirror pairs" (X,Y), where the enumerative geometry (e.g. quantum cohomology) of X controls the complex geometry of the mirror dual Y...

I'll introduce a class of cluster patterns for tensor data used in pattern matching, outlier detections, statistics and signal processing. Then I will show they are all shadows of a general pattern detected efficiently by algebra, specifically Lie...

Introduction to knowledge graph with an application in Construction Code Compliance with BIM and Linked Building Data Abstract: Knowledge graph and ontology are powerful mathematical constructs that has a lot of applications. This presentation begins...

Abstract: Invariant random subgroups are conjugation invariant measures on the space of subgroups of a given group G. Their study provides a fertile playground for the interaction of algebra, geometry, probability and ergodic theory. On one hand...
