On dimensions of block algebras

Markus Linckelmann

Research output: Contribution to journalArticle

Abstract

Following a question by B. K¨ulshammer, we show that an inequality, due to
Brauer, involving the dimension of a block algebra, has an analogue for source algebras, and use this to show that a certain case where this inequality is an equality can be characterised in terms of the structure of the source algebra, generalising a similar result on blocks of minimal dimensions.
