Existence of Mild Solutions and Approximate Controllability of Stochastic Mixed Voltera - Fredholm Type Nonlinear Third-order Dispersion Equation
摘要
In this study, we investigated stochastic mixed Voltera - Fredholm type nonlinear third-order dispersion equation within Hilbert spaces. Initially, we establish the existence of mild solutions to the equation by applying Schauder’s fixed point theorem, properties of infinite-dimensional semigroups, and methods from stochastic analysis. Subsequently, we derive a novel set of sufficient conditions that ensure the Approximate Controllability of the primary system. To demonstrate the practical use of the main result, an example is presented.
