Abstract: Asymptotic estimates are obtained for a complete linearly independent set of solutions of a linear system of differential equations of the form

$\displaystyle y'(t) = [A + V(t) + R(t)]y(t),$

where $ A$ is a constant $ n \times n$ matrix with $ n$ distinct eigenvalues, $ R(t)$ is an integrable matrix valued function on $ (0,\infty )$ and $ V(t)$ is an $ n \times n$ matrix valued function having certain differentiability properties. The theorem that is obtained generalizes a theorem of N. Levinson, Duke Math. J. 15 (1948), 111-126.
