Lethbridge Number Theory and Combinatorics Seminar: Nicol Leong
December 3, 2025
University of Lethbridge
We investigate the sums of reciprocals to an arithmetic progression taken modulo one, that is sums of fractional parts 1/{na−y}, where a,y are real parameters. Such upper bounds are known in the literature, with many applications in number theory...

The PIMS Postdoctoral Fellow Seminar: Felix Christian Clemen
December 3, 2025
Online
A classical problem in combinatorial geometry, posed by Erd\H{o}s in 1946, asks to determine the maximum number of unit segments in a set of $n$ points in the plane. Since then a great variety of extremal problems in finite point sets have been...

PIMS-CORDS SFU Operations Research Seminar: Yuan Zhou
December 2, 2025
Online
In this talk, we study cut-generating functions in the setting of the Gomory-Johnson group relaxations for integer programming. We address an open question: whether every facet (extreme function) for a finite cyclic group relaxation injects into the...

UVictoria Women in Math Lecture Series: Niki-Myrto Mavraki
December 2, 2025
University of Victoria
Iteration has revealed mathematical structure for millennia—from ancient Babylonian root-finding techniques to the intricate fractals developed by Fatou and Julia during the First World War. Yet many mysteries remain. One such puzzle centers on...

Diagram Categories in Homotopy Theory CRG Seminar: Steven Amelotte
December 2, 2025
Online
Toric topology assigns to each simplicial complex K a space with a torus action, called the moment-angle complex, which is defined as a polyhedral product or (homotopy) colimit over the face category of K. These spaces play a universal role in toric...

Math Circles Winter 2025/2026 Session 5
December 1, 2025
University of British Columbia
Students of grades 5 to 7 are invited to challenge and develop their thinking and creativity skills at the Math Circle Workshops. This is an enrichment program for students organized by the faculty members of the Department of Mathematics at the...

Joint Maud Menten /Math Bio Seminar: Jeremy Fox
December 1, 2025
University of Alberta
Random fluctuations in environmental conditions (environmental stochasticity) are thought to increase population extinction risk. But as gamblers, politicians, and sports teams know, even bad risks become good risks when you are facing imminent...

UBC Math Bio Seminar: Wenzheng Shi
December 1, 2025
University of British Columbia
Cells constantly reorganize the actin cytoskeleton to break symmetry, align with neighbors, and push their edges forward. There is a lot of quantitative data on these processes, but turning such data into testable mechanistic models remains a...

47th Australasian Combinatorics Conference
December 1–5, 2025
Te Herenga Waka - Victoria University of Wellington
The Australasian Combinatorics Conference (ACC) is the annual conference of the Combinatorial Mathematics Society of Australasia (CMSA). It covers all areas of combinatorics in mathematics and computer science. It began in 1972, and was previously...

ELMACON 2026 - Preparation Session 1
November 29, 2025
University of British Columbia
ELMACON preparation sessions are free events which take place in the lead up to the ELMACON competition. At each session, an instructor students you through past ELMACON questions and teaches them techniques for tackling them. Subjects covered...
