SCHUR ALGEBRAS OF FINITE TYPE
Copyright policy )SCHUR ALGEBRAS OF FINITE TYPE
Let \(K\) be an algebraically closed field of characteristic \(p>0\), and let \(S_K(n,r)\) be the Schur algebra. The purpose of the paper under review is to classify the Schur algebras of finite type. An algebra is of finite type if it has finitely many indecomposable modules, up to isomorphism. The author shows that the Schur algebra \(S_K(n,r)\) is of finite type if and only if one of the following holds: (1) \(n=2\) and \(r
