Title: Behavior at infinity of psi-evanescent solutions to linear
differential equations
Author: Pham Ngoc Boi (Vinh Univ., Vinh City, Vietnam)
Abstract:
In this article we present some necessary and sufficient
conditions for the existence of $\psi$-evanescent solution of the
nonhomogeneous linear differential equation $x'=A(t)x+f(t)$, which
is related to the notion of $\psi$-ordinary dichotomy for the
equation $x'=A(t)x$. We associate that with the condition of
$\psi$-ordinary dichotomy for the homogeneous linear differential
equation $x'=A(t)x$.
