Abstract:  Using a version of Beilinson's Equivalence Theorem we describe `the framed moduli spaces' of rank one torsion-free coherent sheaves over the quantum projective plane associated with homogenized Weyl algebra. Ring-theoretically, this can be reinterpreted as classifying, up to isomorphism, the ideals in the usual complex Weyl algebra. Such moduli spaces turn out to have a simple and regular structure, strikingly similar to the structure of the usual Hilbert scheme of points on the (commutative) affine plane. The talk is based on joint work with G.Wilson (Imperial College, London).
