Highest Weight Modules and $b$-Functions of Semi-invariants
Introduction 0.1.In [8], we have given an irreducibility criterion for the generalized Verma modules in terms of the b-functions of semi-invariants.(See (2.4) for generalized Verma modules, (2.5) for semi-invariants, and (3.2) for b-functions.)Thus, in order to give explicit information about the irreducibility of the generalized Verma modules, it is necessary …
