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.

Totally unimodular constraint matrices have been used for decades to model many problems in combinatorial optimization; these matrices are particularly useful as then integer programs can be solved as linear ones. Recent results, in particular one...

Peter Borewein empirically discovered quite a number of mysteries involving sign patterns of coefficients of polynomials of the form $f_{p,s,n}(q):=\prod_{j=0}^{n} \prod_{k=1}^{p-1} (1-q^{pj+k})^{s}$ ($p$ a prime and $s,n \in \mathbb{N}$). In the...

Let $\sigma^*(n)$ be the sum of all unitary (i.e. coprime) divisors of $n$. As an analogue of Lehmer’s totient problem, Subbarao proposed the following conjecture. The congruence $\sigma^*(n)\equiv 1\pmod{n}$ is possible iff $n$ is a prime power...

The Pythagorean theorem, dating back to before 500 BC, gives a formula for computing the Euclidean distance between two points. It is simply astounding that a concept so simple and classical has continued to fascinate mathematicians over the ages...

Curvature is one of the fundamental ingredients in differential geometry. People are increasingly interested in whether it is possible to think of combinatorial graphs as manifolds and a number of different notions of curvature have been proposed. I...

While mathematical models have classically been used in the study of physics and engineering, recently, they have become important tools in other fields such as biology, ecology, and sociology. In this talk I will discuss the use of partial...

A set {a1,a2,…,am} of distinct positive integers is a Diophantine m-tuple if the product of any two distinct elements in the set is one less than a square. There is a long history and extensive literature on the study of Diophantine tuples and their...

The random connection model (RCM) is a random graph model where the vertices are given by a Poisson point process with a given intensity, λ>0, and the edges exist independently with a probability that depends upon the relative positions of the two...

The ability to learn and remember is an essential property of the brain that is not limited to high-level processing. In fact, the perception of olfactory stimuli in rodents is strongly shaped by learning processes in the olfactory bulb, the very...

Given two sets X, Y in R^d, such that X isn't contained in a k-plane, we show that there exists a point x in X such that the radial projection pi_x (Y) has Hausdorff dimension > min(dim(X), dim(Y), k) - eps, for any given eps > 0. This improves a...

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).
