Piao, Daxiong Pseudo almost periodic solutions for the systems of differential equations with piecewise constant argument \([t + 1/2]\). (English) Zbl 1217.34105 Sci. China, Ser. A 47, No. 1, 31-38 (2004). Summary: We investigate the existence and uniqueness of pseudo almost periodic solutions and unboundedness of other solutions for the systems of differential equations with piecewise constant argument \([t + 1/2]\) by means of new notion of pseudo almost periodic vector sequences. The case in which the characteristic equation has multiple roots is considered.
