✦ Synopsis

Let k be a finite field and assume that ⌳ is a finite dimensional associative Ž . k-algebra with 1. Denote by mod ⌳ the category of all finitely generated right ⌳-modules and by ind ⌳ the full subcategory in which every object is a representa-Ž . tive of the isoclass of an indecomposable right ⌳-module. We are interested in number of the submodules U of M such that U , N and MrU , L.
