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.

For a number field K, the P\'olya group of K, denoted by Po(K), is the subgroup of the ideal class group of K generated by the classes of the products of maximal ideals of K with the same norm. In this talk, after reviewing some results concerning Po...

Szemerédi's regularity lemma and its variants are some of the most powerful tools in combinatorics. For example, Szemerédi used an early version in the proof of his celebrated theorem on long arithmetic progressions in dense sets of integers. It has...

Matroids are combinatorial objects that abstract the notion of independence. The motivating examples are matroids arising from vector configurations. An important tool for studying matroids is the associated Chow ring. A recent result of Adiprasito...

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...

Matroids are combinatorial objects that abstract the notion of independence. Given any matroid, Feichtner and Yuzvinsky defined a graded commutative ring called the Chow ring, inspired by algebraic geometry. To each matroid, we can define a linear...

Join us for a unique opportunity to meet and learn from Dr. James Glazier, a pioneer in computational biology and a renowned cell and tissue modelling expert. Dr. Glazier’s visit will feature a full day of activities, including a showcase of our...

We discuss the Bunkbed Conjecture, a long-standing conjecture about connection probabilities in percolation. We describe a recent counterexample to this conjecture, a graph on 7772 vertices, and describe its structure.

This will be an in-person version of a Zoom workshop to be given at Grad and Postdoc Studies in December. It is open to all grad students and postdocs, not just those on the job market this year. Please come, learn, ask questions afterwards and give...

I will give an overview of forthcoming work proving that large critical percolation clusters in high-dimensional lattices converge under rescaling to the expected universal limit object: superBrownian motion. A key step is to compute the first-order...

In 1973, assuming the Riemann hypothesis (RH), Montgomery studied the vertical distribution of zeta zeros, and conjectured that they behave like the eigenvalues of some random matrices. We will discuss some models for zeta zeros - starting from the...

The Poisson boundary of a random walk on a group is a probability space used to study the long-term behavior of the random walk. Because the group naturally acts on the Poisson boundary, various questions regarding the structure of this action can be...

A fundamental aim of evolutionary biology is to describe and explain biodiversity patterns; this aim centers around questions of how many "species" exist, where they are most/least abundant, how this distribution is changing over time, and why...

The Hecke orbit conjecture predicts that Hecke symmetries characterize the central foliation on Shimura varieties over an algebraically closed field k of characteristic p. The original conjecture predicts that on the mod p reduction of a Shimura...

The evolution and maintenance of cooperation is a fundamental problem in evolutionary biology. Because cooperative behaviors impose a cost, Cooperators are vulnerable to exploitation by Defectors that do not pay the cost to cooperate but still...

Students of grades 5 to 7 are invited to challenge and develop their thinking and creativity skills at the Math Circle Workshops. Students of grades 5 to 7 are invited to challenge and develop their thinking and creativity skills at the Math Circle...

Single particle cryo-EM is an increasingly popular technique for determining 3-D molecular structures at high resolution. The 2017 Nobel Prize in Chemistry was awarded to three of the pioneers of cryo-EM, and already in the early stages of the global...

This talk introduces a mathematical theory of developmental biology, based on optimal transport. While, in principle, organisms are made of molecules whose motions are described by the Schödinger equation, there are simply too many molecules for this...

We describe a solution to the inverse problem of constructing diffusions and random walks with prescribed sub-Gaussian heat kernel bounds with given volume growth and escape time profiles.

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
