Scientific General Events

  • The Canadian Conference on Computational
    Geometry (CCCG) focuses on the mathematics of discrete geometry from
    a computational point of view. Abstracting and studying the geometry problems
    that underlie important applications of computing (such as geographic information
    systems, computer-aided design, simulation, robotics, solid modeling, databases,
    and graphics) leads not only to new mathematical results, but also to improvements
    in these application areas. Despite its international following, CCCG maintains
    the informality of a smaller workshop and attracts a large number of students.

  • The second PIMS GIW will be held on the University of Calgary Campus in
    August of 2006. Like the first event (2003), the purpose is to bring
    together mathematicians and geophysicists to focus on a challenging
    inversion theme. The theme of the 2006 meeting is "seismic imaging and wave
    propagation". There are a number of invited speakers whose research has been
    especially relevant to the event theme. A limited number of contributed
    papers will also be accepted. Attendance at the GIW is open to all.

  • The Canadian Quantum Information Students' Conference (CQISC) offers
    the ideal environment for graduate students interested in all areas of
    Quantum Information Theory and Experiment to meet an collaborate.
    Students of computer science, mathematics, philosophy, and physics from
    across Canada and around the world are invited to attend.

    delegates are encouraged to present a 30 minute talk on their area of
    research. Previous topics have included topological quantum computing,
    pseudo-telepathy & quantum game theory, measurement based quantum
    computing, quantum chaos, optical lattices, nuclear magnetic resonance,
    quantum authentication & cryptography, quantum error correction,
    and much much more!

  • 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
    codes, and pseudocodewords. We aim to bring together mathematicians and
    engineers, and to increase the pool of early career researchers who
    appreciate the power of discrete mathematics and the important role that it
    plays in emerging engineering disciplines. We will also host a broad
    forward-looking discussion that will address identification of outstanding
    problems, the different forms of publication in constructive combinatorics,
    and reward systems across industry and academia.

    In parallel with the conference, Robert Calderbank (Princeton University)and Ingrid Daubechies (Princeton University) will each deliver a PIMS Distinguished Lecture.

    Limited support is available, especially for students, postdoctoral fellows,
    and other early career researchers.

    The conference will take place the week after the
    2006 IEEE International Symposium on Information Theory in Seattle and the
    9th meeting of the Canadian Number Theory Association in Vancouver.

  • The 2006 Western Canada Linear Algebra Meeting (WCLAM) will be held at the University of Victoria in room C112 of the David Strong Building on June 23-24, 2006. This is the seventh in a series of meetings that have been held since 1993; the previous meetings were held in Regina, Lethbridge, Kananaskis, Victoria, Winnipeg and Regina. WCLAM primarily provides an opportunity for mathematicians and other researchers in western Canada working in linear algebra and related fields to meet, present accounts of their research, and to have informal discussions. While the meeting has a regional base, it also attracts researchers from outside the geographical area, and everyone is welcome to attend and to give presentations.

    This meeting will honour Pauline van den Driessche on the occasion of her sixty fifth birthday.

  • The conference is intended to cover recent
    developments in the study of motives and
    periods with an emphasis to the connections to
    physics, arithmetic and algebraic cycles.
    The conference has an instructional component
    which consists of a series of survey
    talks. The conference will provide an opportunity for
    young speakers to present their results.
    The organizers intend to pay special attention to the
    support of women for this conference, at the senior level
    as well as at the level of postdocs and graduate students.

  • The 34-th Annual Canadian Operator Symposium (COSy) will take place
    at the University of Calgary campus from May 29th to June 2, 2006.

    The meeting will be an occasion to celebrate the 65-th birthday of
    , University of Toronto.

  • This will be the fifth of a sequence of conferences on Scientific Computing and
    Applications held in the Pacific Rim region. All of them have the goal of bringing
    together mathematicians, scientists and engineers working in the field
    of scientific computing and its applications to solve scientific and industrially
    oriented problems and to provide a forum for the participants to meet and
    exchange ideas of common interest in an informal atmosphere.

    The focus of this particular conference will be on the problems and methods
    related to image processing, financial applications and modelling of
    multiphase flows.
    The goal of the conference is twofold.
    The theoretical areas of interest include
    fundamental methods and algorithms for solving PDE's and linear systems
    of equations. On the other hand, it will try to attract the attention of
    the applied community, in particular the oil sands industry, banking
    and medical imaging, to present and discuss the applications of scientific
    computing to practical problems. The theoretical topics of interest are
    (but not limited to): Finite Element, Finite Volume Element and Finite
    Volume Methods for partial differential equations, splitting techniques
    and stabilized methods, iterative solvers and preconditioning techniques
    for large scale systems, methods for systems with a special structure,
    parallel algorithms and performance analysis.

  • MindRap uses an innovative learning process that involves technology, music, art, performing, writing, collaboration, culture, self-esteem, and mentoring. High school students learn how to create animated multimedia modules that include their own artwork, music, and stories to teach a basic math or science skill. Cultural information and achievements are used to motivate and inspire both the students who are creating the modules as well as those who are the intended audience. Throughout the process the students are guided by professional writers, artists, musicians, and educators. The student's creations are then published on a website portal that can be accessed by teachers and students all the over the world. The target of the after school program is at-risk inner city students. We will discuss this project and the various branches of work that have sprouted from its core.

  • On behalf of the University of Alberta, the Department of Mathematical and Statistical Sciences invited the mathematical graduate student community to the 2006 Young Researchers Conference for Mathematical and Statistical Sciences.

    A Stringy Product for Twisted Orbifold K-theory

    Given an orbifold X with inertia orbifold LX, we construct a product for the twisted K-theory of LX which extends the orbifold cohomology product of Chen & Ruan. The twisting arises from the "inverse transgression" of elements in $H^4(BX, Z)$. This is joint work with Y.Ruan and B.Zhang.

    Global convergence of the Yamabe flow

    Let $M$ be a compact manifold of dimension $n \geq 3$. Along the Yamabe flow, a Riemannian metric on $M$ is deformed such that $\frac{\partial g}{\partial t} = -(R_g - r_g) \, g$, where $R_g$ is the scalar curvature associated with the metric $g$ and $r_g$ denotes the mean value of $R_g$. It is known that the Yamabe flow exists for all time. Moreover, if $3 \leq n \leq 5$ or $M$ is locally conformally flat, then the solution approaches a metric of constant scalar curvature as $t \to \infty$. I will describe how this result can be generalized to higher dimensions. The key ingredient in the proof is a new construction of test functions whose Yamabe energy is less than that of the round sphere.

    Donaldson-Thomas and Gromov-Witten invariants of orbifolds and their crepant resolutions

    A well known principle in physics asserts that string theory on an orbifold X is equivalent to string theory on Y, any crepant resolution of X. Donaldson-Thomas and Gromov-Witten theory are mathematical counterparts of type IIA and type IIB topological string theory and so it is expected that one can recover the Gromov-Witten or Donaldson-Thomas invariants of Y from those on X. We will mathematically formulate and discuss these correspondences and illustrate them with some examples.

    Lagrangian currents, Calabi invariants and non-simpleness of the area-preserving homeomorphism group of S^2

    In this talk, I will introduce the notion of `hamiltonian limits' of the Hamiltonian flows, and define the continuous Hamiltonian flows and their associated Hamiltonian functions, which I call `topological Hamiltonians'. I will give the proof of the uniqueness of the topolocgical Hamiltonian associated to continuous Hamiltonian flows. The uniquessness proof uses the method of geometric measure theory and some $C^0$ symplectic geometry. I will discuss some implication of this study in a well-known conjecture in the dynamical systems on the simpleness of the area preserving homeomorphism group $S^2$.
