摘要
分析研究离散四阶差分方程周期解的多重性,应用三临界点定理处理四阶差分方程的周期解,得到了多重周期解的存在性结果.
In this paper, we deal with the Multiplicity of periodic solutions for a discrete fourth order difference equation. A multiple result is obtained for periodic solution of fourth order difference equations by the three critical points theorem.
