Abstract
In this paper we continue the study of solvability of the non-homogeneous system of linear differential equations
in the space of all rapidly decreasing functions, whereC(t) is a continuous square matrix of ordern for allt ∈ ℝ, whose elements are all unbounded functions on the real line ℝ. We give a necessary and sufficient condition in order that the system (1) be solvable in this space.
