Tilting modules for quantum groups

introduction

modules for \(U_q(\mathfrak{g})\)
Verma modules \(M_{\lambda}=U_q(\mathfrak{g})\otimes_{U_q(\mathfrak{b})}\mathbb{C}_{\lambda}\)
Weyl modules : quotients of Verma modules

\[ W_{\lambda}=M_{\lambda}/\operatorname{span}(M_{s_i\cdot \lambda}) \]

a tilting module is a module \(T\) that admits a filtration whose associated graded pieces are Weyl modules and that admits another filtration whose associated graded are dual Weyl modules
