Convergence Theorems for Generalized Functional Sequences of Discrete-Time Normal Martingales (1510.04639v1)
Published 15 Oct 2015 in math.PR and math.FA
Abstract: The Fock transform recently introduced by the authors in a previous paper is applied to investigate convergence of generalized functional sequences of a discrete-time normal martingale $M$. A necessary and sufficient condition in terms of the Fock transform is obtained for such a sequence to be strong convergent. A type of generalized martingales associated with $M$ are introduced and their convergence theorems are established. Some applications are also shown.
