PIMS Network Wide Colloquium | PIMS - Pacific Institute for the Mathematical Sciences

In 2021, PIMS inaugurated a high-level network-wide colloquium series. For this series, distinguished speakers give talks across the full PIMS network with one talk per month during the academic term.

These seminars will be available online. Please see our notes on effective virtual events for tips on getting the most out of our online events. The seminars will be recorded, and the recordings will be available on mathtube.org.

The Monge transfer problem goes back to the 18th century. It consists in minimizing the transport cost of a material from a place to another (and changing the shape). Monge could not solve the problem and the next significant step was achieved 150...

Gauge-theoretic moduli spaces are often noncompact, and various techniques have been introduced to study their asymptotic features. Seminal work by Taubes shows that in many situations where the failure of compactness for sequences of solutions is...

Recent progress in model theory is changing our understanding of how the finite and infinite interact. One aspect of this story has to do with the emerging appearance of complexity in so-called simple unstable theories, which provide a model...

In the Lipschitz extension problem we are given a pair of metric spaces X,Y and ask for the smallest K such that for any subset A of X every L-Lipschitz mapping from A to Y can be extended to a KL-Lipschitz mapping from X to Y. Most of this talk will...

In The Hitchhiker’s Guide to the Galaxy, by Douglas Adams, the number 42 was revealed to be the “Answer to the Ultimate Question of Life, the Universe, and Everything”. But he didn’t say what the question was! I will reveal that here. In fact it is a...

The asymmetric exclusion process (ASEP) is a model of particles hopping on a one-dimensional lattice. While it was initially introduced by Macdonald-Gibbs-Pipkin to provide a model for translation in protein synthesis, the stationary distribution of...

Abstract : Colour {1,..,N} red and blue, in such a manner that no 3 of the blue elements are in arithmetic progression. How long an arithmetic progression of red elements must there be? It had been speculated based on numerical evidence that there...

Due to unforseen circumstances, this talk has been cancelled and will be rescheduled for a future date. We apologize for the inconvenience. Speaker Abstract: Diffusion methods help understand and denoise data sets; when there is additional structure...
