Title Extensions of graded affine Hecke algebra modules
Date 2014-12
Description In this dissertation, we study extensions of graded ane Hecke algebra modules. In particular, based on an explicit projective resolution on graded ane Hecke algebra modules, we prove a duality result for Ext-groups. This duality result with analysis on some parabolically induced modules gives a new proof of the fact that all higher Ext-groups between discrete series vanish. Finally, we study a twisted Euler-Poincare pairing and show the pairing depends on the Weyl group structure of graded ane Hecke algebra modules.
