Organizational Meeting

We will discuss/determine the time this seminar will be held this term as well as determine the first set of speakers. If you wish to have input or wish to talk and are unable to attend please contact Robert Harris or Yash Singh.

MC 5403

Stuart White, Oxford University

"Simple amenable C*-algebras"

C*-algebras are norm closed self-adjoint algebras of bounded operators on Hilbert space, and so arise naturally from unitary representations of groups and group actions, amongst other constructions. Large scale work of many researchers over decades has recently culminated in a definitive classification theorem for simple amenable C*-algebras of finite topological dimension.

Organizational Meeting

We will discuss the format of the seminar and potential goals for the semester.

MC 5403

Tomer Zimhoni, Ben Gurion University

"Random Permutations from Free Products"

Talk #1 (1:00-2:30pm)

Ruxandra Moraru, Department of Pure Mathematics, University of Waterloo

"Hitchin pairs on higher-dimensional manifolds"

Moshe Kamensky, Ben-Gurion University

"Higher internal covers"

In model theory, internality is a relationship between definable sets that entails the existence of a definable Galois group, with definable Galois correspondence. It can be formulated as an equivalence between certain expansion of a theory T (internal covers) and groupoids definable in that theory. I will describe a partial generalisation of this correspondence to higher dimensions.
