In this paper, we present a theorem on the almost periodic solutions of second-order neutral equations with piecewise constant arguments of the form where [β’] denotes the greatest integer function, p, q (| p| > 1 or p = -1) are nonzero constants, and f (t) is almost periodic.
We study the existence of quasi-periodic solutions to differential equations with piecewise constant argument (EPCA, for short). It is shown that EPCA with periodic perturbations possess a quasi-periodic solution and no periodic solution. The appearance of quasi-periodic rather than periodic solutio
