Abstract.  In this article, a class of fractional integro-differential equations of mixed type is considered and some sufficient conditions in connection with the existence of integral solutions are established with the help of the fixed point theorems due to Banach, Krasnoselskii and Darbo-Sadovskii,and also the fixed point theorem for condensing maps. Two of the results are verified by considering appropriate examples.
Keywords: Volterra-Fredholm integro-differential equation, Hille-Yosida condition, integral solution, fixed-point theorem, measure of noncompactness.
