“K-theory of graph C*-algebras : Crossed product preliminaries”

In this talk we will give a rather quick introduction to crossed product C* algebras. We will mainly focus on the case of abelian groups and look at some examples

MC 5417

Michael Deveau, Department of Pure Mathematics, University of Waterloo

“Pseudo-Jump Inversion - Part II”

Spiro Karigiannis, Pure Mathematics Department, University of Waterloo

“Differential Analysis IV: Thom-Smale Transversality”

Adam Dor On, Department of Pure Mathematics, University of Waterloo

“K-theory for graph C*-algebras”

After we’ve dealt with some K-theory, we introduce another six-term exact sequence due to Pimsner and Voiculescu in the context of graph algebras. We use our combined knowledge on K-theory and graph algebras to start computing the K-theory of a graph C*-algebra.

MC 5417

Anton Borissov, Pure Math Department, University of Waterloo

“Divisors on Toric Varieties II”

After briefly reviewing what we did in the first talk, we will move on to discuss the orbit- cone correspondence, Weil divisors, and Cartier divisors on toric varieties. Time permitting we shall talk about how to compute the divisor class group and the Picard group on a toric variety.

“Some Highly Influential and Extremely Important Short Presentations.”

5 accomplished speakers. 5 minutes each. 1 hilarious afternoon.

Russell Miller, Queens College - City University of New York

"Effective Classification of Computable Structures”

Anton Borissov, Pure Math Department, University of Waterloo

“Divisors on Toric Varieties”

Toric Varieties are geometric objects that are described by combinatorial data. Their description allows one to compute many geometrical quantities in a straightforward fashion. In this talk we will define toric varieties and work towards describing the global sections of line bundles on them.
