Abstract
This work concerns the existence of almost periodic solutions for
certain di erential equations with piecewise constant arguments. The coef-
cients of these equations are almost periodic and the equation can be seen
as perturbations of a linear equation satisfying an exponential dichotomy on
a di erence equation. The stability of that solution on a semi-axis is also
studied.
