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.

Given a graph G, its genus distribution is the sequence whose k-th term is the number of 2-cell embeddings of G in the orientable surface of genus k. The Log-Concavity Genus Distribution (LCGD) Conjecture states that the genus distribution of every...

This talk will discuss two inference problems in dynamical systems, both motivated by applications in mathematical biology. First, we will discuss the classical gene regulatory network inference problem for time-stamped single-cell datasets and...

Mathematical modeling, when combined with diverse epidemiological datasets, provides valuable insights for understanding and controlling infectious diseases. In this talk, I will present a series of case studies demonstrating how the synergy between...

In two independent papers, Aizenman and Fröhlich argued that every scaling limit of the critical Ising model in dimensions d > 4 is trivial (or Gaussian). This qualitative result can be reformulated as follows: the Schwinger functions of any...

Talk Abstract The orthogonally projected shadows of a dispersed set in the plane carry much of the information about the shape of the set. The average size of the shadow, known as the Favard length, can be used to study density, structure...

Conifold transitions are a mechanism in which a Calabi-Yau 3-fold is deformed into another by contracting curves and smoothing out the resulting conical singularities. Reid's Fantasy conjectures that all Calabi-Yau 3-folds can be linked by a sequence...

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...

Let X be an isotropic unimodal L\'{e}vy jump process on ℝ d . We develop probabilistic methods which in many cases allow us to determine whether X satisfies the elliptic Harnack inequality (EHI), by looking only at the jump kernel of X , and its...

The van Eeden seminar is a yearly event in which graduate students vote for their favorite statisticians. The winner is contacted by the organizing committee and invited to give a talk in the department’s seminar. The speaker spends one or two days...

In 1966, Tate proposed the Artin-Tate conjectures, which expresses special values of zeta function associated to surfaces over finite fields. Conditional on the Tate conjecture, Milne–Ramachandran formulated and proved similar conjectures for smooth...

In this talk, I will present a roadmap for deriving minimal necessary conditions for diffusion-driven instability for a 3-component reaction-diffusion system with linear cross-diffusion. For the reaction kinetics, we postulate and formulate a new 3...

We present generalizations and modifications of Eldan's Stochastic Localization process, extending it to incorporate non-Gaussian tilts, making it useful for a broader class of measures. As an application, we introduce new processes that enable the...

This alternative math education event will present fun activities to explore math and computer science concepts to children (and adults!) using games and art! Lots of hands-on activities including: Sorting network An impossible balancing act...

I'll introduce a class of cluster patterns for tensor data used in pattern matching, outlier detections, statistics and signal processing. Then I will show they are all shadows of a general pattern detected efficiently by algebra, specifically Lie...

While the etale cohomology of Z/p-local systems on smooth p-adic rigid spaces is in general hard to control, it becomes more tractable when the spaces are proper. For example, in the proper case it is finite-dimensional and has recently been shown in...

A big conjecture which emerged from the math-physics interface is that the Gromov-Witten potentials of a Calabi-Yau threefold are generalized quasi-modular objects. In on-going work, joint with Aaron Pixton, we study the case of Picard rank 3 Abelian...

The discrete Schrödinger equation on a two-dimensional honeycomb lattice is a fundamental tight-binding approximation model that describes the propagation of electrons on graphene. By the Fourier transform on the honeycomb lattice, the free...

Hierarchical percolation is a toy model for percolation on ℤd that, much like the Euclidean model, is expected to exhibit mean-field behavior in high dimensions, non-mean-field behavior in low dimensions, and mean-field behavior with logarithmic...

Many modern data science tasks can be expressed as optimizing a complex, random function in high dimensions. The go-to method for such problems is Stochastic gradient descent (SGD), which performs remarkably well—c.f. the success of modern neural...

The PIMS offices 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.

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

ArriveCan

Travelling between UBC and SFU by bus

There are many public transit options for travel between UBC and SFU but please note the universities are at opposite ends of Vancouver (SFU is actually in Burnaby) and travel can take an hour or more. Visit Translink for more travel options.
