    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.

    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.

    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.

  • During the last few years, the workshop has facilitated discussions on a variety of topics of interest to college and university faculty. Topics in the past have included connections between automorphic forms and other areas or mathematics, how to find the right job, encouraging and retaining under-represented groups in number theory, grant writing, how to choose the right journal, and balancing a career with a personal life.


    Based on the success of previous sessions, we plan to hold discussions again this year. 

  • Abstract:

    Central to Alan Turing's posthumous reputation is his work with British codebreaking during the Second World War. This relationship is not well understood, largely because it stands on the intersection of two technical fields, mathematics and cryptology, the second of which also has been shrouded by secrecy. This lecture will assess this relationship from an historical cryptological perspective. It treats the mathematization and mechanization of cryptology between 1920-50 as international phenomena. It assesses Turing's role in one important phase of this process, British work at Bletchley Park in developing cryptanalytical machines for use against Enigma in 1940-41. It focuses on also his interest in and work with cryptographic machines between 1942-46, and concludes that work with them served as a seed bed for the development of his thinking about computers.


  • Cellular reconstitution: Rebuilding biological systems from the bottom-up


    Abstract:Understanding the molecular basis of cellular behaviour is a central goal in biology and a critical guide for medical research. Increasing knowledge of the essential proteins in a complex process such as crawling motility raises the tantalizing question: Do we know enough to build it? In vitro reconstitution provides an import tool for identifying the roles of individual molecules, but defining components is not enough. Progress towards reconstitution of micron-scale cellular structures and processes has been limited by the challenges of generating in vitro reconstitutions that capture the spatial organization, physical constraints, and dynamics of living cells. This talk will describe on-going efforts to create functional reconstitutions of cytoskeletal and membrane processes involved in cellular protrusions and membrane transport. The lessons of what works – and what doesn’t – are helping to guide efforts to build biological systems from molecular parts.

  • The Eleventh Colloquiumfest will present talks on valuation theory, number
    theory and algebraic geometry.
