Blocks with defect group ${\mathbb{Z}}_{2^n}\times {\mathbb{Z}}_{2^n}\times {\mathbb{Z}}_{2^m}$

Abstract

In this paper, we prove that a block with defect group ${\mathbb{Z}}_{2^n}\times {\mathbb{Z}}_{2^n}\times {\mathbb{Z}}_{2^m}$, where $n\ge 2$ and $m$ is arbitrary, is Morita equivalent to its Brauer correspondent.
