Abstract

Using the method of exponential dichotomies, we establish a new existence and uniqueness theorem of almost automorphic solution for differential equations with piecewise constant argument of the form \(x'(t)=A(t)x(t)+B(t)x([t])+f(t), \quad t\in\mathbb{R},\)where \([\cdot]\) denotes the greatest integer function, and \(A(t), B(t):\mathbb{R}\to\mathbb{R}^{q\times q}\), \(f(t):\mathbb{R}\to\mathbb{R}^q\) are all almost automorphic.
