Unicity on Entire Function Concerning Its Differential-Difference Operators

Abstract

In this paper, we study the uniqueness of entire function and its differential-difference operators. We prove the following result: let f be a transcendental entire function of finite order, let \(\eta \) be a non-zero complex number, \(n\ge 1, k\ge 0\) two integers and let a and b be two distinct finite complex numbers. If f and \((\Delta _{\eta }^{n}f)^{(k)}\) share a CM and share b IM, then \(f\equiv (\Delta _{\eta }^{n}f)^{(k)}\).
