A representation for the logarithmic derivative of a meromorphic function

Morris Marden

Vol. 38 (1971), No. 1, 145–149
Abstract

A new representation is developed for the logarithmic derivative of a meromorphic function f in terms of its zeros and poles, using as parameters some of the critical points of f. Applications are made to locating all but a finite number of critical points of f.
