Characteristic polynomials of finitely generated modules over Weyl algebras
Published online by Cambridge University Press: 17 April 2009
Abstract
In this paper we modify the classical Gröbner basis technique and prove the existence of a characteristic polynomial in two variables associated with a finitely generated module over a Weyl algebra. We determine invariants of such a polynomial and show that some of the invariants are not carried by the Bernstein dimension polynomial of the module.
