On subnormal solutions of periodic differential equations. Chen, Zong-Xuan; Shon, Kwang Ho — 2010 Abstract and Applied Analysis
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 ) .
