“…1. In previous papers ( [1], [2]) we considered the differential equation: n dw ( m 2 n 2 2 l and defined two solutions P%-n (z) and Q™ >n {z) of (1) for all points of the z-plane in which a crosscut exists along the real axis from 1 to -oo. In [3] we gave tables of expansions for these functions in terms of hypergeometric functions F{a, b; c; £}, where £ is a linear function of z.…”
