On the modular isomorphism problem for groups with center of index at most $p^{3}$

Sofia Brenner, Diego García-Lucas

Let $p$ be an odd prime number. We show that the modular isomorphism problem has a positive answer for finite $p$ -groups whose center has index $p^{3}$ , which is a strong contrast to…

Ideals in the center of symmetric algebras

Sofia Brenner, Burkhard Külshammer

We study symmetric algebras $A$ over an algebraically closed field $F$ in which the Jacobson radical of the center of $A$ , the socle of the center of $A$ or the Reynolds ideal of $…
