Scientific General Events
The PIMS YRC is a unique and important opportunity for young graduate students in mathematics and statistics from PIMS universities to meet their peers and discover the wide range of research currently undertaken in Western Canada and the Pacific Northwest. Participants will have opportunities to build and strengthen personal and professional relationships, develop and improve communication skills, and gain valuable experience in the environment of a scientific conference.
This conference has grown from the collaboration between the universities of Alberta and Calgary into a truly inter-PIMS universities project. The PIMS YRC 2012 will offer: An overview of current mathematical research at PIMS universities, an opportunity to present a short talk in a professional context, a panel discussion on employability in both industry and academia, a chance for graduate students to start building their scientific network, and plenary talks by leading mathematical experts in their fields.Since its inception in 2004 by graduate students at the University of Alberta, the PIMS YRC has been held alternately at the University of Alberta, the University of Calgary, and last year in 2011, the PIMS YRC was hosted for the first time outside of Alberta at the University of British Columbia. The conference has become a well-recognized and popular event; in 2007 the CYRC boasted over 90 participants from 11 different universities and in 2008 welcomed participants from six different provinces from across Canada. The PIMS YRC will continue to gain momentum, respect, and popularity among young researchers in mathematics and statistics.
The stability of coherent structure and patterns.
Stability plays an essential role in many branches of science and engineering, including several aspects of fluid mechanics, high-speed transmission of information, and feasibility of MHD fusion devices. The objective of the workshop is to give an overview of current state-of-the-art methods for examining stability, as well as to present some widely applicable new techniques. The format will consist of three invited speakers giving a series of lectures at a level aimed at graduate students but useful for researchers from a variety of disciplines, such as mathematics, engineering, biology, etc.
There will be two main courses, given by Omer Angel and Gregory Miermont. There will be a number of invited talks. Participants will have an option of giving a presentation as well.
Omer Angel - Interacting particle systems
Particles attempt to follow a simple dynamic (random walk, constant flow, etc) in some space (interval, line, cycle, arbitrary graph). Add a simple interaction between particles, and the behaviour can change completely. The resulting dynamical systems are far more complex than the ingredients suggest. These processes (interchange process, TASEP, sorting networks, etc) have diverse to many topics: growth processes, queuing theory, representation theory, algebraic combinatorics. I will discuss recent progress on and open problems arising from several models of interacting particle systems.
Gregory Miermont - Planar Maps
The study of maps, that is of graphs embedded in surfaces, is a popular subject that has implications in many branches of mathematics, the most famous aspects being purely graph-theoretical, such as the four-color theorem. The study of random maps has met an increasing interest in the recent years. This is motivated in particular by problems in theoretical physics, in which random maps serve as discrete models of random continuum surfaces. The probabilistic interpretation of bijective counting methods for maps happen to be particularly fruitful, and relates random maps to other important combinatorial random structures like the continuum random tree and the Brownian snake. This course will survey these aspects and present recent developments in this area.
This is a satellite event to the 2012 Summer Meeting of the Canadian Mathematical Society that will take place from June 2 to 4, and it will continue into that meeting as a Special Session on the same topic.
This workshop will introduce participants to current research topics in the intersection of Algebra and Geometry
The symposium encompasses all aspects of
multiple-valued logic, including but not limited to:
and Formal Aspects
Systems and Soft Computing
Design and Switching Theory
Learning and Robotics
Abstracts for the talks:
1. Toti Daskalapoulos
Title: Ancient solutions of the Yamabe flow
Abstract: We construct new ancient compact solutions of the Yamabe flow. Our approach involves a parabolic analogue of the gluing method of solutions to the rescaled flow with constant scalar curvature.
2. Eric Bahuaud
Title: The Yamabe flow of an incomplete edge metric
Abstract: In this talk I will describe recent work to understand the behaviour of the Yamabe flow in a singular setting modeled by an incomplete edge metric. I will discuss the background estimates obtained from the heat kernel, conditions for short-time existence and prospects for long-time existence. This is ongoing work with Boris Vertman.
3. Martin Li
Title: Minimal Surfaces with Free Boundary and Geometric Applications
Abstract: Minimal surfaces have been a very useful tool in studying 3-manifold topology and geometry since the pioneering work of Schoen-Yau. When the 3-manifold M possess a boundary, it is natural to look at minimal surfaces with free boundary. In this talk, I will first describe a very general existence result for properly embedded minimal surfaces with free boundary. When the 3-manifold satisfies some curvature and boundary convexity assumptions, we show that the space of these minimal surfaces with a fixed topological type is compact in a very strong sense. As a geometric application, we prove a rigidity result for bounded convex domains in R^3 in terms of the area of a minimal surface which realize the "width" of the convex domain. If time permits, I will indicate some potential applications to mean curvature flow in R^3.

Title : Collapsing with a lower bound on the curvature operator
Abstract : Cheeger and Gromov characterized bounded curvature collapse in terms of F-structures. I'll describe how some of the Cheeger-Gromov results extend to collapse with just a lower bound on the curvature operator, in terms of fibered F-structures.

Title: Analysis on smooth metric measure spaces and applications
Abstract: We intend to explain some joint work with Ovidiu Munteanu concerning the analysis on smooth manifolds with densities.Applications to the Ricci gradient solitons will also be discussed.
The Alberta Colleges Mathematics Conference presents talks about the teaching issues specific to the colleges and their math course offerings. This is an opportunity to meet with colleagues from Alberta’s post-secondary institutions primarily, discuss teaching, technology, and curriculum, and to share perspectives on experiences and common interests of mathematics in Alberta.
The North/South Dialogue, also sponsored by PIMS, will take place Friday, running concurrently with the Colleges Mathematics Conference. This year we will feature two parallel sessions (program details will follow).
This event will celebrate Dale Rolfsen's 70th birthday.
There will be a special conference dinner.
