| Abstract: | In this paper we describe a tensor space representation of theblob algebra over a ring allowing base change to every interesting(that is, non-semisimple) specialisation. We show that in quasihereditaryspecialisations this passes to a full tilting module. We considerthe nature of the resultant Ringel dual algebra. 2000 MathematicsSubject Classification 20C08. |
