##### Speaker

Dr Adam Sierakowski (University of Wollongong)

##### Title

Twisted groupoids

##### Abstract

I will discuss some of the basic aspects of a twisted groupoid G and its associated C*-algebra. In particular I will define the line bundle associated to G, its structure as a Fell bundle over G, and show how a twisted groupoid C*-algebra of a trivial twist is a groupoid C*-algebra of a relation.
