Title: Units of (twisted) group rings and twisted isomorphism problems

Abstract: In the first part of the talk  we will introduce a new approach to study units of integral group rings using integral twisted group rings and their units.

In the second part of the talk we will talk about some new results concerning the twisted version of the classical group ring isomorphism problem, mainly, over finite fields.

The first part is a joint work with Geoffrey Janssens and second part is a joint work with Leo Margolis.
