Ofir Schnabel, Twisted group ring isomorphism problem.

Abstract:
We propose and study a twisted variation of the classical isomorphism problem for group rings. We formulate several weaker conditions following from our notion and give all logical connections between these conditions. We introduce methods to study the problem and provide results for various classes of groups, including abelian groups, groups of central type, p-groups of order p⁴ and groups of order p²q², where p and q denote different primes.
Joint work with Leo Margolis.
