Abstract
We introduce the notions of a weak periodic system and its generalized-periodic motions. Such systems include systems generated by ordinary differential equations, equations with retarded argument, Volterra type equations, etc. We present a criterion for the existence of generalized-periodic motions and establish their main properties.Keywords
