S-asymptotically omega-periodic solution for a nonlinear differential equation with piecewise constant argument via S-asymptotically omega-periodic functions in the Stepanov sense (1711.03768v1)

Abstract: In this paper, we show the existence of function which is not S-asymptotically omega-periodic, but which is S-asymptotically omega-periodic in the Stepanov sense. We give sufficient conditions for the existence and uniqueness of S-asymptotically omega-periodic solutions for a nonautonomous differential equation with piecewise constant argument in a Banach space when omega is an integer. This is done using the Banach fixed point Theorem. An example involving the heat operator is discussed as an illustration of the theory.
