Some Aspects of the Anticipating Calculus for the Poisson Process

Abstract: We use the Poisson-Ito chaos decomposition approach to define a variational derivative operator and its adjoint, which is an anticipating integral, i.e., agrees with the martingale Poisson-Ito integral with respect to the compensated Poisson process for predictable integrands. In the case where the basic probability space is the canonical Poisson space, our derivative operator is egual to the Carlen and Pardoux gradient operator that is defined by means of variation of the jump times.
