On $L_p$-Solvability of Stochastic Integro-Differential Equations (1907.04876v1)
Published 10 Jul 2019 in math.AP and math.PR
Abstract: A class of (possibly) degenerate stochastic integro-differential equations of parabolic type is considered, which includes the Zakai equation in nonlinear filtering for jump diffusions. Existence and uniqueness of the solutions are established in Bessel potential spaces.
