DNA topology is the study of the geometry (supercoiling) and topology (knotting and linking) of DNA. Knots and links in DNA are known to obstruct normal cellular processes and geometric factors such as the amount of writhe or supercoiling are known...

One way to define an integer polymatroid ρ is via its independent set polytope, whose faces are parallel translations of the independent set polytopes of the minors of ρ. To better understand the interior of this polytope, we endow a structure on...

The Math2Power Quantum summer school on quantum computing will be held across 2 days (May 29 and 30) in the lead up to the CMS Summer Meeting and is aimed at helping students in the mathematical sciences learn - through a combination of lectures and...

In this talk, I will discuss a long-standing problem on type II singularity of Ricc flow. First I recall some known results on long-time behavior of Ricci flow, then I will present our solution to the above problem. I may also discuss a related...

We'll talk about a piece of mathematics bringing together number theory (Ivan Niven's subject), geometry, and dynamical systems, that exemplify many of the things I love about math - community, diversity, collaboration, beautiful images, and an...

On May 25th, Math Challengers and ELMACON are inviting volunteers to come to UBC for a workshop on creating new problems for these two contests. For over 20 years, these contests have challenged students with creative and innovative questions, aiming...

This event will be a special iteration of the Western Canada Linear Algebra Meeting (WCLAM) to honour Peter Lancaster at 95. There is a large and thriving Linear Algebra community in Western Canada, where there is ongoing research in matrix analysis...

Over the past few years, operator learning – the approximation of mappings between infinite dimensional function spaces using ideas from machine learning – has attracted increased research attention. Approximate operators, learned from data, hold...

Optimal transport operates on empirical distributions which may contain acquisition artifacts, such as outliers or noise, thereby hindering a robust calculation of the OT map. Additionally, it necessitates equal mass between the two distributions...

In this talk, we consider colored permutation groups ℤm≀Sn, which contain the symmetric groups Sn≅ℤ1≀Sn and the signed symmetric groups Bn≅ℤ2≀Sn as special cases. Like in Sn, colored permutations in ℤm≀Sn have a notion of cycle type that classifies...
