Almost Periodic Solutions for a Second-Order Nonlinear Equation with Mixed Delays

“…Dads and Lhachimi [6] obtained some necessary and sufficient conditions in order to ensure the existence and uniqueness of pseudo almost periodic solutions for a second-order differential equation with piecewise constant argument. For more results about almost periodic solution of differential equations and dynamic system, see [7][8][9]. In [10][11][12], almost periodic solutions in Banach spaces have been studied.…”
