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

Registration for the 2025/26 Network-Wide Colloquium Series is open.

This online series features distinguished speakers each month during the academic term — highlighting important developments across the mathematical sciences.

Whether you are a long-standing member of the PIMS community or discovering the series for the first time, the Network-Wide Colloquium provides an opportunity to engage with leading researchers and connect across disciplines and institutions.

Registration is required only once and provides access to all talks. Participants are encouraged to download the calendar information to save the dates; Zoom event reminders will be sent prior to each talk. Seminars are also recorded and available on mathtube.org.

Upcoming Events

Immune cell infiltration in solid tumours was once regarded as clear evidence of the body’s attempt to eradicate a malignant threat. It is, however, now well established that tumours can co-opt immune cells, reprogramming them from tumour-suppressive...

Past Events

Integer lattices play a central role in mathematics and computer science, with applications ranging from number theory and coding theory to combinatorial optimization. Over the past three decades, they have also become a cornerstone of modern...

How does one describe the structure of a graph? What is a good way to measure how complicated a given graph is? Tree decompositions are a powerful tool in structural graph theory, designed to address these questions. To obtain a tree decomposition of...

Join us for a the first colloquium with Professor Curtis McMullen, Fields Medalist and professor of mathematics at Harvard University. In this talk, titled "The Question Mark Function, Welding, and Complex Dynamics," Prof. McMullen will explore a...

Long DNA and RNA molecules encode the genetic code of viruses and living organisms. We study the changes in DNA topology mediated by essential processes such as DNA packing and transcription of DNA into RNA. These processes are highly regulated, and...

The array 3 -3 4 -4 5 -5 0 0 4 -4 -3 3 0 0 5 -5 -5 5 0 0 -3 3 -4 4 has an interesting feature: its columns are each vectors satisfying the linear relation 3x + 4y + 5z = 0...

I will discuss a result with Bonatti and Crovisier from 2009 showing that the C^1 generic diffeomorphism f of a closed manifold has trivial centralizer; i.e. fg = gf implies that g is a power of f. I’ll discuss features of the C^1 topology that...

Finding and enumerating Boolean intervals in $W(\mathfrak{S}_n)$, the weak order of symmetric group $\mathfrak{S}_n$, can feel like trying to find needles in a haystack. However, through surprising connection to the outcome map of parking functions...

When particles interact with attractive-repulsive dynamics, which can model birds flocking, space dust, or a variety of other phenomena, they tend to form a nice distribution. Understanding these distributions is an active area of applied analysis...

For centuries, mathematicians have relied on computers to perform calculations, to suggest conjectures, and as components of mathematical proofs. In the light of more modern tools such as interactive theorem provers, machine learning algorithms, and...

We will introduce the research area of complex dynamics by studying the family of (complex) quadratic polynomials, $z->z^2+c$. Historically, mathematicians first studied the dynamics of {\em real} quadratic polynomials and then moved to the complex...
