Title | Bases for projective modules in An (k) | Author(s) | Gago-Vargas | Type | Article in Journal | Abstract | Let An(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 M is projective and rank(M) ≥ 2 we give a procedure to find a basis. | Keywords | | Length | 9 | ISSN | 0747-7171 | Copyright | Elsevier Ltd. |
