Recently, Mohar introduced a variant of the cops and robber game that is played on geodesic spaces. In this talk we discuss the rules of the game and strategies for the players when the game is played on compact surfaces of constant curvature, in...

I will discuss my joint work with José Carrillo on a large family of Riesz-type singular interaction potentials with anisotropy in two dimensions. Their associated global energy minimizers are given by explicit formulas whose supports are determined...

When we iterate functions over finite structures, there is an underlying natural functional graph. For a function $f$ over a finite field $\mathbb{F}_q$, this graph has $q$ nodes and a directed edge from vertex $a$ to vertex $b$ if and only if $f(a)...

Martingales are perhaps best known as a gambling strategy of repeatedly doubling the stakes of a bet, in the hope that eventually a single win will cover previous losses and return a profit. In physics, though little known, martingales are also...

In this lecture, I will focus on formulating a dynamical geometric surface partial differential equation for modelling static images during the process of single or collective cell migration. In the absence of detailed experimental molecular and...

Bilevel optimization has been widely used in a variety of areas such as adversarial training, hyperparameter tuning, image reconstruction meta-learning, neural architecture search, and reinforcement learning. In this talk, I will present first-order...

From a directed graph $Q$, called a quiver, one can construct what is known as a quiver variety $Y_Q$, an algebraic variety defined as a quotient of a vector space by a group defined in terms of $Q$. A mutation of a quiver is an operation that...

As the underlying configuration behind many elegant finite structures, partial difference sets have been intensively studied in design theory, finite geometry, coding theory, and graph theory. In the first part of this talk, I will showcase that...

SFU's Association for Women in Mathematics Student Chapter, in collaboration with the Department of Mathematics EDI Advisory Group, is hosting a series of events for the International Women in Mathematics Day. The celebration begins with a Women’s...

The objective of this conference is to bring together researchers, postdoctoral fellows, recent graduates in the fields of statistics, machine learning and optimization to foster collaboration, exchange ideas, and promote the advancement of research...
