A Simple Technique for Solving Partial Differential Equations on Surfaces

Many applications require the solution of time dependent partial differential equations (PDEs) on surfaces or more general manifolds. Methods for treating such problems include surface parameterization, methods on triangulated surfaces and embeddi   more››

Mechanistic Images in Geometric Form: Heinrich Hertz's Principles of Mechanic

During the last three years of his life Heinrich Hertz wrote a treatise on mechanics which was to be the last attempt to supply a satisfactory foundation to classical mechanics. It was published posthumously in 1894, the year of his death.   more››

Feasible Proofs and Computations

The concepts of proof and computation are central to virtually any intellectual human activity. However, before the remarkable advances of the 20th century mathematical logic, the border between them had never been sharp even in the context of pur   more››

Scientific Event

Glacier and ice sheet dynamics

Glaciers and ice sheets are thin viscous gravity currents subject to mass sources and sinks due to surface snow accumulation and melting. Mathematically, the evolution of glacier geometry poses interesting free boundary problems. Land-based glaciers   more››

Optimal Drug Therapy for Chronic Myelogenous Leukemia

Drug therapy is introduced as a control in a mathematical model for chronic myelogenous leukemia (CML). The cancer is modeled as a system of ODE's representing the dynamics between the immune systen in the body and cancer cells. We introduce two cont   more››

A Polymer Model Explains MinDE Dynamics in E. coli Cell Division

In Escherichia coli, the location of the site for cell division is regulated by the action of the Min proteins. These proteins undergo a periodic pole-to-pole oscillation that involves polymerization and ATPase activity of MinD under the controlling   more››

Scientific Event

Going with the (Information) Flow: on efficient computations & boundary value problems.

The direction of information propagation can be used to de-couple certain systems of nonlinear equations. This fundamental principle is the basis of Dijkstra's classical method for finding shortest paths on graphs. We will use the continuous analogue   more››

Applied Math Show and Tell

The first annual applied math show and tell will be an opportunity graduate students and other faculty to learn about what faculty in the applied math group are doing. Each speaker will have under five minutes to give a one paragraph intro to their r   more››

Image and Video Special Effects based on Geometry and Partial Differential Equations

Scientific Event

Three-dimensional Turing patterns: Stability, implications in biological modeling, and equilibrium

Turing patterns are structures that can form spontaneously in systems of reacting and diffusing chemicals. Since the 1950s, when Alain Turing first put forth the theoretical considerations, there has been a vast amount of literature on the subject. I   more››

CECM Summer Meeting 2006

CECM, Maplesoft, MITACS, IRMACS and PIMS are pleased to present "CECM 2006", a summer conference hosted by CECM under the title "Summer Workshop on Computational Mathematics" at Simon Fraser University. The Workshop   more››

Scientific Event

Heisenberg-Weyl groups and their application to sequence design

We will describe how Heisenberg-Weyl groups appear in the construction of phase coded radar waveforms, in the design of spreading sequences in wireless communications, and in the theory of classical and quantum error-correcting codes. Interesti   more››

Question and Answer Session

A rare event for students (undergraduate and graduate) to meet two of the most acclaimed mathematical scientists of our time. PIMS invites you to attend a special informal question & answer session with these speakers after their lectures, to be   more››

Introduction to Wavelets

Wavelets are a new approach used in the analysis of sounds and images, as well as in many other applications. The wavelet transform provides a mathematical analog to a music score: just as the score tells a musician which notes to play whe   more››

Sequences and Codes

The conference will explore new research directions within the fields of sequence design and algebraic error-correcting codes, including radar applications of sequence design, algebraic constructions of space-time   more››

Some arithmetic problems raised by rabbits, cows and the Da Vinci Code

In 1202, the Italian mathematician Leonardo da Pisa, alias Fibonacci, introduced a sequence of numbers that nowadays bears his name. Under the assumption that rabbits breed (producing a pair of rabbits) when   more››

The Physics of Eternity

The Physics of Eternity Recent evidence points to an open universe, where time might run forever. If we take the current laws of physics, and run things forward, what could we see of the far future? We find some predictions out to 10**15 years are fa   more››

Scientific Event

Polynomials, Permutations, Prime Ideals, and factoring Polynomials modulo p

The talk began as an attempt to answer the following question - if f(x) is an irreducible polynomial with integer coefficients, does it remain irreducible modulo p for infinitely many primes p? It turns out that the answer is sometimes yes and som   more››
