    Quasi-free divisors and duality  [Article]

    Castro Jiménez, Francisco Jesús; Ucha Enríquez, José María (Elsevier, 2004)

    On some D-modules in dimension 2  [Article]

    Castro Jiménez, Francisco Jesús; Ucha Enríquez, José María (Cornell University, 2000)
    We prove a duality formula for two D-modules arising from logarithmic derivations w.r.t. a plane curve. As an application we give a differential proof of a logarithmic comparison theorem in [4].
