Bilateral set-valued stochastic integral equations

Abstract

We investigate bilateral set-valued stochastic integral equations and these equations combine widening and narrrowing set-valued stochastic integral equations studied in literature. An existence and uniqueness theorem is established using approximate solutions. In addition stability of the solution with respect to small changes of the initial state and coefficients is esablished, also we provide a result on boundedness of the solution, and an estimate for a distance between the exact solution and the approximate solution is given. Finally some implications for deterministic set-valued integral equations are presented.
