Rutkauskas, S. On a weighted boundary value problem for a system of linear ordinary differential equations with a singularity. I. (Russian. English summary) Zbl 0677.34018 Lit. Mat. Sb. 29, No. 1, 109-122 (1989). Summary: A system of second order differential equations with an irregular singular point is considered. The fundamental system of matrix-solutions is constructed. The asymptotics of these solutions and their derivatives in a neighbourhood of the singular point are considered.
