We prove necessary and sufficient conditions for Ψ − (uniform) stability of the trivial solution of a nonlinear Lyapunov matrix differential equation. But the obtained results in
In this paper we consider the Cauchy problem for a nonautonomous second order differential- delay equation and derive conditions that provide the positivity of the Green function..
