Kuznetsov, P. I.; Yudina, A. S. Asymptotic expansions of the solutions of a degenerate hypergeometric equation. (Russian) Zbl 0627.34010 Differ. Uravn. 23, No. 3, 428-434 (1987). The fundamental system of solutions of \(zw''+(b-z)w'-aw=0\) in the complex plane z are found in asymptotic form. The complex parameters a and b are assumed large in the neighbourhood of the regular singular point z.
