UBC Math Bio Seminar: Belinda Akpa
March 20, 2024
University of British Columbia
At a time when many are wrangling with biological ‘big data’, there remain important problems that are fundamentally data limited – often physiological questions for which there is little quantitative data, and further data collection may be hampered...

Lethbridge Number Theory and Combinatorics Seminar: Sarah Dijols
March 20, 2024
University of Lethbridge
I will explain how the Geometric Lemma allows us to classify parabolically induced representations of the p-adic group $G_2$ distinguished by $SO_4$. In particular, I will describe a new approach, in progress, where we use the structure of the p-adic...

URegina Topology & Geometry Seminar: Mahmoud Zeinalian
March 20, 2024
University of Regina
I will review some of the basic machinery used in formulating characteristic classes for coherent sheaves on complex manifolds. The main ideas go back to the fundamental work of Toledo and Tong in the 70s. A natural extension of their ideas leads to...

The PIMS Postdoctoral Fellow Seminar: Kesav Krishnan
March 20, 2024
Online
In this talk, I will describe how certain non-linear exponential tilts of the Discrete Gaussian Free Field yield invariant measures for a discretized PDE, the focusing Non Linear Schr\”odinger equation. I will briefly talk about how this tilted...

SFU Mathematics of Computation, Application and Data ("MOCAD") Seminar: Silas Polani
March 18, 2024
Simon Fraser University
Intraguild predation (IGP) consists of two (or more) consumers of the same shared resource exhibiting a predator-prey relation among themselves, and is a very present phenomena in terrestrial, freshwater and marine ecological systems. Theoretical...

UBC Harmonic Analysis and Fractal Geometry: Junjie Zhu
March 18, 2024
University of British Columbia
The notions of Hausdorff and Fourier dimensions are ubiquitous in harmonic analysis and geometric measure theory. It is known that any hypersurface in ℝd+1 has Hausdorff dimension d. However, the Fourier dimension depends on the finer geometric...
Scientific, Seminar
L-functions in Analytic Number Theory: Quanli Shen
March 18, 2024
University of Lethbridge
I will discuss the fourth moment of quadratic Dirichlet L-functions where we prove an asymptotic formula with four main terms unconditionally. Previously, the asymptotic formula was established with the leading main term under generalized Riemann...

POSTPONED: Land and Sea: Mathematics of the Climate Crisis-A Global Conversation
March 18, 2024
Online
POSTPONED: Unfortunately this event has been postponed at short notice. It will no longer take place on March 18th, but will be rescheduled for later in the summer About Land and Sea: Mathematics of the Climate Crisis-A Global Conversation is the...
Scientific, Colloquia
PIMS/UBC Mathematical Sciences Early Career Award Colloquium: Trevor Campbell
March 15, 2024
University of British Columbia
Since shortly after the popularization of stochastic gradient optimization methods in machine learning---which now scale model training to billions of examples and beyond---researchers have been trying to use the same basic data subsampling...

UVic-PIMS Data Science Seminar: Lin Zhang
March 15, 2024
University of Victoria
Single-cell omics data play a pivotal role in identifying cell-to-cell heterogeneity, understanding cell differentiation, unveiling cell population structures, and ultimately deciphering disease pathogenesis. Due to inherent high-dimensionality...
