Functions that Share Two Finite Values with Their Derivative

S. Tanaiadchawoot

Abstract


The purpose of this paper is to study a meromorphic functions which share two finite nonzero values with their derivatives, and the result is proved: Let f be a nonconstant meromorphic function, a, b be a nonzero distinct finite complex constant. If f and f ' share a CM, and share b IM and $\bar{N} (r, f) = S(r, f)$ then f = f '.
