On the zeros of (f″ + αf)f and a result of Steinmetz
Published online by Cambridge University Press: 14 November 2011
Synopsis
We characterise all functions f meromorphic of finite order in the plane such that fF has only finitely many zeros, where F = f″ + αf for some constant α. The problem is related to results of N. Steinmetz and others.
