Abstract.  In this paper, we investigate the existence and controllability of a class of fractional integro-differential equations with infinite delay and a weakly singular kernel in the setting of Banach spaces. The analysis is primarily developed through the framework of semigroup theory, in conjunction with Mönch’s fixed point theorem and the properties of measures of noncompactness. To validate the theoretical findings, a carefully constructed example is provided, demonstrating the applicability and effectiveness of the proposed approach.
Keywords: Functional integro-differential equations; mild solution; semigroup; Banach space; controllability; singular kernels.
