Ulam Stabilities via Pachpatte's Inequality for Volterra-Fredholm Delay Integrodifferential Equations in Banach Spaces

In this paper, we will investigate Ulam-Hyers and Ulam-Hyers-Rassias stabilities of nonlinear Volterra-Fredholm delay integrodifferential equations in Banach spaces. Pachpatte's inequality and its extended version are utilized to obtain these stabilities. Examples are given in support of the results we obtained
