A study of nonlinear impulsive fractional integro-differential equations with unbounded delay

In this paper, we construct sufficient conditions for the existence and uniqueness of solutions to impulsive nonlinear neutral fractional integro-differential equations with infinite delay complemented with nonlocal boundary conditions with the aid of the Krasnoselskii fixed point theorem and the contraction mapping principle.Examples are also provided to illustrate the main results presented in this paper.
