In this paper we push forward results on the invariant F-module of a
virtual knot investigated by the first named author where F is the
algebra with two invertible generators A,B and one relation
A−1B−1AB−B−1AB=BA−1B−1A−A. For flat knots and links the two
sides of the relation equation are put equal to unity and the algebra becomes
the Weyl algebra. If this is perturbed and the two sides of the relation
equation are put equal to a general element, q, of the ground ring, then the
resulting module lays claim to be the correct generalization of the Alexander
module. Many finite dimensional representations are given together with
calculations.Comment: 18 pages, 5 figures, accepted by Journal of Geometry and Physic
