Endomorphism algebras of some modules for Schur algebras and representation dimension
 
 
Description:  This is joint work with H. Geranios. In a recent paper Miemietz and Oppermann show that, for fixed n\geq 2, the representation dimension of the Schur algebra S(n,r) goes to infinity with r, under certain characteristics restrictions. We show that this the result is valid without characteristic restrictions. Our methods are quite different. We make use of the representation theory of the first infinitesimal subgroup of the general linear group and our arguments are valid also for q Schur algebra.
