Let K be a field. Let H be a finite-dimensional K-Hopf algebra and D(H) be the Drinfel’d double of H. In this paper, we study Radford’s induced module Hβ, wh
For a finitely generated module M over a commutative Noetherian local ring (R, m), it is shown that there exist only a finite number of non-isomorphic top local
An explicit construction of indecomposable modules for the twisted Heisenberg Virasoro algebra and representations for the full toroidal Lie algebras are given.
