Given 8 linear differentid equation of the form dn) + 131 (t)z("'l) + . -+ a,,(t)z = 0 with variable coefficients defined on the poaitive aemi-sxis for t > 1. We denote its fundamental aet of solutions (FSS) by {exp [Jri(t) dt] } (i = 1,2,. . . ,n). In this paper we look for the asymptotic connectio
