Abelian invariants and a reduction theorem for the modular isomorphism problem

Leo Margolis, Taro Sakurai, Mima Stanojkovski

We show that elementary abelian direct factors can be disregarded in the study of the modular isomorphism problem. Moreover, we obtain four new series of abelian invariants of the…

Non-isomorphic 2-groups with isomorphic modular group algebras

Diego García, Leo Margolis, Ángel del Río

We provide non-isomorphic finite 2-groups which have isomorphic group algebras over any field of characteristic 2, thus settling the Modular Isomorphism Problem.
