Blocks with abelian defect groups of rank 2 and one simple module
Abstract
In this paper, we investigate the block that has an abelian defect group of rank $2$ and its Brauer correspondent has only one simple module. We will get an isotypy between the block and its Brauer correspondent. It will generalize the result of Kessar and Linckelmann (\\cite{KL}).
