Complex Variables 2014-12-30 v1

Abstract

In this paper, we prove some uniqueness results which improve and generalize several earlier works. Also, we prove a value distribution result concerning f(k)f^{(k)} which provides a partial answer to a question of Fang and Wang [A note on the conjectures of Hayman, Mues and Gol'dberg, Comp. Methods, Funct. Theory (2013)13, 533-543].
