Consider the differential equation

1.1

where

1.2

is regular in |z| < R.

The indicial equation associated with (1.1) is of the form

We shall denote the two roots of this equation by α and β, where . Corresponding to the root α there exists a unique solution of (1.1) of the following form

1.3

In those cases for which there exists a unique second solution of (1.1) of the form
