Nilpotent group codes
André Duarte, Alexandra da Silva Pereira, César Polcino Milies · Journal of Algebra and Its Applications · 2022
In this paper, we consider essential idempotents in the finite semisimple group algebra of a nilpotent group, studying conditions for their existence and other implications. Also, we discuss conditions for nilpotent group codes to be equivalent to Abelian ones.
