Where isomorphisms of group algebras fail to lift

Leo Margolis, Taro Sakurai

Counterexamples to the Modular Isomorphism Problem were discovered recently. These are non-isomorphic finite -groups and that have isomorphic group algebras over the fie…

The Modular Isomorphism Problem over all fields

Leo Margolis, Taro Sakurai

The Modular Isomorphism Problem asks, if an isomorphism between modular group algebras of finite -groups over a field implies an isomorphism of the group bases. We explore t…
