Abstract

We have explored sufficient conditions for the controllability of fractional-order Sobolev-type neutral functional integro-differential equations involving the Atangana-Baleanu-Caputo (ABC) derivative. Our approach integrates key concepts from semigroup theory, the contraction mapping principle, measures of noncompactness, and standard fixed point techniques. The theoretical results are further illustrated through a concrete example, validating the applicability of the proposed framework.
