Let A n (k) be the Weyl algebra, with k a field of characteristic zero. It is known that every projective finitely generated left module is free or isomorphic to a left ideal. Let M be a left submodule of a free module. In this paper we give an algorithm to compute the projective dimension of M. If
We consider a condition on a group G, that was studied by Strebel and independently by Strojnowski, which implies that the complex group algebra of G has no non-trivial idempotents. We elaborate on that technique and slightly relax the Strebel-Strojnowski condition. This enables us to prove in a rel
