摘要
In this paper, we study the existence of entire solutions of finite-order of non-linear difference equations of the form f n (z) + q(z) c f (z) = p1ea1z + p2ea2z, n = 2 and f n (z) + q(z) eQ(z) f (z + c) = p1e.z + p2e -.z, n = 3 where q, Q are non-zero polynomials, c,., pi, ai (i = 1, 2) are non-zero constants such that a1 = a2 and c f (z) = f (z+ c)-f (z) = 0. Our results are improvements and complements ofWen et al. (Acta Math Sin 28: 1295-1306, 2012), Yang and Laine (Proc Jpn Acad Ser A Math Sci 86: 10-14, 2010) and Zinelaabidine (Mediterr J Math 14: 1-16, 2017).
