University of British Columbia | PIMS - Pacific Institute for the Mathematical Sciences

The University of British Columbia PIMS site office is located in the Earth Sciences Building at the University of British Columbia.

The University of British Columbia PIMS site office also hosts the PIMS central offices. These are located on the 4th floor of the Earth Sciences Building (2207 Main Mall). If using the elevator, our offices will be directly across when you get to the 4th floor. If using the main staircase, the offices will be to your right once you reach the 4th floor.

The Tutte polynomial of a graph is a two-variable polynomial, which is the universal polynomial satisfying deletion contraction recursion. In this talk I will explain how this polynomial arises from considering the cohomology of hypertoric varieties...

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...

We will briefly describe our own use of AI tools in research, software, writing, supervision and administration, and raise some questions about what this will do to publishing, training and the profession.

Understanding how cells change over time is fundamental to studying development, differentiation, and regeneration. Recent advances in single-cell genomics provide detailed measurements of cellular states, but these measurements are typically limited...

Perfect codes in the Hamming metric over prime power alphabets were completely classified in the 1970s. For more general alphabets, analogous classifications were obtained for such codes correcting at least three errors. The case of 2-error...

The forum will explore a range of academic career paths, including research-stream positions at research-intensive universities, educational leadership positions, and positions at teaching-focused universities and colleges. The speakers will bring...

How different are two shapes? If each shape is represented as a point cloud, optimal transport (OT) gives a natural answer: find the matching between points that minimizes the average displacement. But OT depends on how the shapes are positioned...

In this talk, I'll describe some approaches to agentic ai for exploratory research, for facilitating understanding of mathematics, for aiding in writing and editing of manuscripts, and some of the ways in which these ideas come together. To...

The moduli space of stable bundles on curves has been extensively studied. Notably, Jeffrey--Kirwan calculated the intersection numbers on this moduli space in terms of iterated residues, first written down by Witten in the physics literature...

I will explore how the geometry of a smooth projective variety X constrains the actions of a finite p-group G on it. The main result is that when X has a Chern number prime to p, any G-action on X factors through a subgroup of GL_n(k), where n = dim...

The simulation of tumour growth presents many challenges from a modelling point of view, both when performing in vitro models and when corresponding to tumours in patients. Obviously, the difficulties are much more relevant for patient-specific...

Precise spatiotemporal patterns of transcription factors (TFs) regulate genes critical for embryo development, instructing cells to differentiate and adopt specific fates. For example, the Homeobox (Hox) TF Ultrabithorax (Ubx) specifies the identity...

The collective migration of embryonic neural crest (NC) cells is an important part of embryonic development. NC cells migrate in streams away from the neural tube along well-defined paths to reach their destination. This results in an essentially one...

Tipping points refer to abrupt, substantial, and often irreversible transitions in dynamic systems that can be triggered by perturbations. Existing tipping mechanisms are usually classified by the nature of the trigger: bifurcation-induced tipping...

Phylogenetic analysis is important for understanding the evolutionary relationships among taxa and is widely applied in epidemiology, evolutionary biology, and conservation. Despite many advances and theories developed, challenges and methodological...

A classical method for exhibiting non-trivial elements in the Tate-Shafarevich group of Jacobians compares Selmer groups of various isogenies. In this presentation we consider Jacobians of plane quartics that have a (2,2,2)-isogeny to another...

Airport to PIMS UBC by Bus

From Vancouver Airport (YVR), take the Canada Line Skytrain to Broadway City Hall Station. Get off the platform and walk up to street level. Cross the street and you should see the #99Bline UBC stop outside the Lululemon store. You can take this bus all the way out to UBC. Detailed route information is available through translink's route planner or via google maps. See translink's fare page for up to date prices.

Airport to PIMS UBC by car

To drive from Vancouver Airport (YVR) to UBC, follow signs for Vancouver City Center when leaving the airport. After crossing the Arthur Laing bridge, follow 70th avenue/Marine Drive all the way out to UBC's Point Grey campus. The PIMS offices are in the Earth Science Building on Main Mall which doesn't permit vehicular traffic. The nearest parking lot (or drop off point for Taxis) is on West Mall near the West Parkade at the intersection of West Mall and Bio. Sciences Road (see this map).

Downtown Vancouver to PIMS UBC by car

When leaving Downtown Vancouver, follow signs for UBC (see this map).

Tsawwassen Ferry Terminal to PIMS UBC by car

Follow directions for Vancouver airport until you reach the City of Vancouver, then follow the directions above for travelling from the airport.

BC Ferries

US Border to PIMS UBC by car

Follow directions for Vancouver until you reach the City of Vancouver, then follow the directions above for travelling to PIMS from the airport. Please make sure you have the correct travel documents and follow instructions
