Colloquium Equivariant Index Theorem and the Van Est Map Xiang Tang (Washington University in St Louis) Thursday, October 31, 2013 at 3:30 pm Tilley Hall Room 5 Let H be a compact subgroup of a Lie group G. When G/H is not compact, G-invariant elliptic operator on G/H in general fails to be Fredholm. In this talk, we will explain an index theorem about such operators using...

Colloquium Non-commutative resolutions of singularities and the global spectrum Eleonore Faber (University of Toronto) Wednesday, November 13, 2013 at 2:30 pm Tilley Hall Room 302 This talk is about non-commutative analogs of resolutions of singularities. In short, non-commutative desingularizations of a commutative ring R are endomorphism rings of certain R-modules of finite global...

Colloquium Vortex Filament Dynamics Walter Craig (McMaster) Thursday, October 10, 2013 at 2:30 pm Tilley Hall Room 125 In this talk I will describe a problem in fluid dynamics concerning the interaction of two near-parallel vortex filaments in three dimensions. This is an example of phase space analysis of a partial differential equation (PDE) that can be formulated as a Hamiltonian...

Colloquium What Happened Before the Big Bang? Martin Bojowald (Penn State) Thursday, November 14, 2013 at 3:30 pm Tilley Hall Room 5 The standard model of cosmology suggests that the universe started with a phase of very high density, described by general relativity as a singularity. Quantum gravity attempts to resolve the singularity by a more fundamental, microscopic theory of...

Graduate Seminar Differential Forms in Topology and Geometry Mohammed Alhumaidi (UNB) Thursday, November 7, 2013 at 3:30 pm Tilley Hall Room 5 We give a brief overview of differential forms and their properties, including Stoke’s theorem. The definition of de Rham cohomology is then given. This is followed by the presentation of two applications: the derivation of the Hopf invariant...

Graduate Seminar Graph C*-Algebras Christopher Chlebovec (UNB) Thursday, October 17, 2013 at 3:30 pm Tilley Hall Room 5 Graph C*- algebras are a class of C*- algebras in which we can associate, to each directed graph, a unique C*- algebra. They encompass a large array of examples and allow us to encode the inherent properties of the C*- algebra by analyzing its corresponding graph. In this...

ColloquiumFinding The Hidden Space Behind Complex Networks: An Approach Using The New Theory Of Graph Limits Jeanette Janssen (Dalhousie) Wednesday, October 9, 2013 at 2:30 pm Carleton Hall Room 306 Many real-life networks can be modeled by stochastic processes with a spatial embedding. In such processes, the link probability decreases with distance. The spatial embedding can be seen...

ColloquiumNoncommutative Rational Singularities Kenneth Chan (University of Washington in Seattle) Thursday, September 12, 2013 at 3:30 pm Tilley Hall Room 125 We introduce the notion of Brauer log pairs and explain their connection with noncommutative algebraic geometry. There is a theory, analogous to the log MMP, which provides terminal models for Brauer log pairs over surfaces. We define...

ColloquiumSingular Differential Equations and the Stokes Groupoids Brent Pym (McGill) Thursday, September 5, 2013 at 3:30 pm Tilley Hall Room 125 Solutions of ordinary differential equations typically behave quite badly near an irregular singular point, exhibiting essential singularities and divergent power series expansions. In recent work with Marco Gualtieri and Songhao Li, we use methods...
