dc.description.abstract | 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 $M$ is projective and $\rk(M) \ge 2$ we give a
procedure to find a basis. | es |
