摘要: 利用Nevanlinna值分布理论,研究了两类非线性微分-差分方程f n+ωf n-1f '+b(f ')n+qeQf(z+c)=uev和f n1f n-1f '+ω2(f ')n+qeQf(z+c)=p1eλ1z+p2eλ2z的有限级整函数解的存在性,得到了两个结果,并举例证明文中所得结果是精确的。

关键词: 非线性微分-差分方程, 整函数解, 主次项, 增长级

Abstract: Using Nevanlinna's value distribution theory, this paper investigates the existence of entire solutions with finite order of two types of nonlinear differential-difference equations of the forms f n+ωf n-1f '+b(f ')n+qeQf(z+c)=uev and f n1f n-1f '+ω2(f ')n+qeQf(z+c)=p1eλ1z+p2eλ2z, and obtains two results. Examples are provided to show that the results obtained in this paper, in a sense, are best possible.

Key words: nonlinear differential-difference equation, entire solution, dominant term, order of growth
