“Purely infinite graph C*-algebras”
Back on the graph algebras track, we will describe necessary and sufficient graph-theoretic conditions for a graph algebra to be AF or purely infinite simple. It will follow that these two classes cover all the simple graph algebras.

“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.

“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.
