Properties of differences of meromorphic functions Zong-Xuan Chen, Kwang Ho Shon (2011) Czechoslovak Mathematical Journal Let f be a transcendental meromorphic function. We propose a number of results concerning zeros and fixed points of the difference g ( z ) = f ( z + c ) - f ( z ) and the divided difference g ( z ) / f ( z ) .
