Community ecology of infectious disease pathogens

January 14, 2025

Room 102: Lecture Theatre - Michael Smith Laboratories

The human population presents a unique ecosystem for studying pathogen communities, with anthropogenic activities like COVID-19 lockdowns serving as large-scale natural experiments. In this talk, I begin by exploring how host immune response facilitate the invasion and persistence of novel... Read more

From Combinatorics to Knot Theory (and Back Again)

January 13, 2025

MATX 1100 and Zoom

Catalan numbers are among the most ubiquitous objects in mathematics, arising naturally in combinatorics, representation theory, geometry, and many other areas. Although there are various polynomial generalizations of these numbers, particularly fruitful are the so-called ( q , t ) -Catalan... Read more

Discrete geometry via semialgebraic graph theory

January 10, 2025

ESB 2012 and Zoom

Many problems in discrete geometry can be conveniently encoded by a structure known as a semialgebraic graph. These problems include the Erdős unit distance problem and many of its variants, point-line incidence problems studied by Szemerédi–Trotter and by Guth–Katz, general problems about... Read more

Ramsey and Turán numbers of sparse hypergraphs

January 9, 2025

MATH 126

The degeneracy of a graph is a measure of sparseness that gives important information about its Ramsey- and Turán-type properties. I will talk about the hypergraph extension of these problems. The typical notion of hypergraph degeneracy does not give any information about either the Ramsey or... Read more

Lonely runners

January 8, 2025

MATH 102 and Zoom

Dirichlet's Theorem, the foundational result of Diophantine approximation, says that for any real number t, there is some natural number v in {1,2,...,n} such that tv lies within 1/(n+1) of an integer. The Lonely Runner Conjecture of Wills and Cusick asserts that the constant 1/(n+1) in this... Read more

Corners with polynomial side length

January 7, 2025

ESB 4133 (PIMS library)

We prove "reasonable" quantitative bounds for sets in Z^2 avoiding the polynomial corner configuration (x,y), (x+P(z),y), (x,y+P(z)), where P is any fixed integer-coefficient polynomial with an integer root of multiplicity 1. This simultaneously generalizes a result of Shkredov about corner-free... Read more

Identifying determinants of long-term viral suppression following broadly neutralizing antibody treatment against HIV-1

January 7, 2025

Room 102: Lecture Theatre - Michael Smith Laboratories

Due to their long circulating half-life, high neutralization potency, and large breadth of coverage, broadly neutralizing antibodies are increasingly studied for the treatment of HIV-1 infection. Recent phase I clinical studies of antibody treatment have demonstrated robust and durable antiviral... Read more

Involutions and the Brauer group in derived algebraic geometry

January 6, 2025

Math 126, Dept. of Mathematics, UBC

Classical results of Albert and Saltman (extended by Knus–Parimala–Srinivas) have established a connection between the existence of (anti-)involutions on the central simple algebras A used to define the Brauer group and 2-torsion Brauer classes. Moreover, the presence of more general forms of... Read more
