摘要
In a recent paper, Hamaya studied the existence of periodic solutions and almost periodic solutions of a system of nonlinear integrodifferential equations under the assumptions that a bounded solution of the system exists and that the solution is stable in some sense. In the present paper Hamaya's results are applied to a system of nonlinear integral equations showing the appropriate conditions to ensure the existence of periodic solutions and almost periodic solutions.
