Özet

In this work, we study the existence, uniqueness, and stability of fractional stochastic pantograph differential equations involving the Caputo fractional derivative. By applying a fixed-point theorem under suitable assumptions, we establish sufficient conditions for the existence and uniqueness of solutions to the proposed equations. Additionally, we prove that the solution is Hyers-Ulam stable. Our results also provide a significant generalization of existing findings in the literature. Finally, a concrete example is presented to illustrate the effectiveness of the obtained results.
