Abstract

In this article, we consider properties of transcendental meromorphic solutions of the complex differential-difference equation $$ P_n(z)f^{(n)}(z+\eta_n)+\cdots+P_1(z)f'(z+\eta_1)+P_0(z)f(z+\eta_0)=0, $$ and its non-homogeneous equation. Our results extend earlier results by Liu et al.~\cite{Liu3}.

Keywords: meromorphic solution, complex differential-difference equation, growth, exponent of convergence of zeros and poles
