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 $x'=A(t)x$. Submitted April 29, 2010. Published July 28, 2010.
