【 摘 要 】

In this paper, we estimate the size of rho(n)'s in the famous L. Zalcman's lemma. With it, we obtain some uniqueness theorems for meromorphic functions f and f' when they share two transcendental meromorphic functions. Crown Copyright (C) 2009 Published by Elsevier Inc. All rights reserved.
