 Uniqueness of entire functions and differential polynomials Bull. Korean Math. Soc. 2007 Vol. 44, No. 4, 623-629 Published online December 1, 2007 Junfeng Xu, Hongxun Yi Shandong University, Shandong University Abstract : In this paper, we study the uniqueness of entire functions and prove the following result: Let $f$ and $g$ be two nonconstant entire functions, $n, m$ be positive integers. If $f^n(f^m-1)f'$ and $g^n(g^m-1)g'$ share 1 IM and $n>4m+11$, then $f\equiv g$. The result improves the result of Fang-Fang. Keywords : uniqueness, entire function, sharing values MSC numbers : 30D35 Downloads: Full-text PDF
