Abstract

Classification, boundedness, and existence of solutions of a second order nonlinear difference equation are investigated. First, it is proved that all  solutions are eventually monotone. Then, the necessary and sufficient conditions for the boundedness of all solutions are established. Finally, the existence of different types of monotonic solutions are presented. The obtained results have extended and improved some existing ones.

二阶非线性差分方程的单调解
研究了一类二阶非线性差分方程的分类、有界性和解的存在性。首先,证明了所有解最终都是单调的。然后,建立了所有解有界性的充分必要条件。最后,给出了不同类型单调解的存在性。所得结果是对已有结果的扩展和改进。
