This is another question I have trouble proving:(adsbygoogle = window.adsbygoogle || []).push({});

Suppose the coefficients of the equation: w'' + p(z)w' + q(z)w = 0 are analytic and single-valued in a punctured neighborhood of the origin. Suppose it is known that the function w(z) = f(z) ln z is a solution, where f is analytic and single-valued in a punctured neighborhood. Deduce that f is also a solution.

Thanks for your help.
