Abstract

We study a class of endomomorphism algebras of certain q q -permutation modules over the Hecke algebra of type B B , whose summands involve both parabolic and quasi-parabolic subgroups, and prove that these algebras are integrally free and quasi-hereditary, and are stable under base change. Some consequences for decomposition numbers are discussed.
