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 Grassmannian manifold of $k$-planes in $\mathbb{R}^n$ has a group action if $\mathbb{R}^n$ is taken to be a real representation of the group. When the group is $C_2$, the Schubert cell construction of the Grassmannian generalizes to an...

We shall give an overview of what Khovanov cohomology and its relatives have told us about knot concordance over the past 15 years. No knowledge required. Includes joint work with Lukas Lewark and Peter Feller.

In an article published in 2009, David Benson described, for a finite group $G$, the mod $p$ homology of the space $\Omega(BG^{\wedge}_p)$ -- the loop space of the $p$-completion of $BG$ -- in purely algebraic terms. In joint work with Carlos Broto...

If E is a compact set of Hausdorff dimension s > 1 on the plane, then its distance set was conjectured (by Falconer 1985) to have positive Lebesgue measure. Joint with Guth, Iosevich and Ou, we show that dim E > 5/4 is a sufficient condition. This...

The standard iterative methods for solving linear and nonlinear systems of equations are all synchronous, meaning that in the parallel execution of these methods where some processors may complete an iteration before other processors (for example...

The conjugate gradient algorithm (CG) is a widely used iterative method for solving large symmetric positive definite linear systems Ax=b. Beginning in the 1980's (and, even earlier, in the thesis of Paige dating back to 1971), a great deal of...

When a group acts faithfully by orientation-preserving homeomorphisms on S^1, one can sometimes use the action on S^1 to prove the existence of a faithful order-preserving action by homeomorphisms on the real line. This can be reworded in algebraic...

There is a rich interplay between the degree of regularity of a group action on the circle and the allowable algebraic structure of the group. I will outline some highlights of this theory, culminating in a construction due to Kim and myself of...

One of the goals of quantum information theory is to understand quantum systems from the standpoint of computational complexity. How difficult is it to compute fundamental properties of a quantum system or simulate a particular system over time...

Cutting plane techniques are key to solving large scale optimization problems with mixed-integer variables. Modern approaches to cutting plane theory shows that the concept of sublinearity is a unifying way to organize these ideas. This leads to 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).
