Almost periodic solutions with a prescribed spectrum of systems of linear and quasilinear differential equations with almost periodic coefficients and constant time lag (Cauchy integral). (English) Zbl 0936.42003

Summary: This paper generalizes earlier author’s results where the linear and quasilinear equations with constant coefficients were treated. Here the method of limiting and a fixed-point theorem is used for the linear and quasilinear equations with almost periodic coefficients.
