The Exact Entire Solutions of Certain Type of Nonlinear Difference Equations
2021
In this paper, we consider the entire solutions of nonlinear difference equation $$f^{3}+q(z)\Delta f=p_{1}e^{\alpha_{1}z}+p_{2}e^{\alpha_{2}z}$$
, where $$q$$
is a polynomial, and $$p_{1},p_{2},\alpha_{1},$$
and $$\alpha_{2}$$
are nonzero constants with $$\alpha_{1}\neq\alpha_{2}$$
. It is showed that if $$f$$
is a nonconstant entire solution of $$\rho_{2}(f)<1$$
to the above equation, then $$f(z)=e_{1}e^{\frac{\alpha_{1}z}{3}}+e_{2}e^{\frac{\alpha_{2}z}{3}}$$
, where $$e_{1}$$
and $$e_{2}$$
are two constants. Meanwhile, we give an affirmative answer to the conjecture posed by Zhang et al in [18].
