Abstract

As a sequel of \citeOu, in this shot note, we investigate block basis for coinvariants of finite modular pseudo-reflection groups. We are particularly interested in the case where G is a subgroup of the parabolic subgroups of GL_n(q) which generalizes the Weyl groups of restricted Cartan type Lie algebra.
