模糊差分方程Xn+1=δn+Xn/Xn-1的动力学性质OA
Dynamical behaviors of fuzzy difference equation Xn+1=δn+Xn/Xn-1
差分方程作为动力系统重要分支之一,一直以来都受到学术界的广泛关注.近年来,由于在应用差分方程解决实际问题时,参数的波动和变化带来了方法的转变,故模糊差分方程的研究引起了该领域众多学者的关注.论文中模糊差分方程Xn+1=δn+Xn/Xn-1,n=0,1,2,…的动力学性质将被展开讨论,其中,初始条件X-1,X0 是正模糊数,参数δn 是 2 周期正模糊数序列.研究得到,该模糊差分方程存在唯一正解Xn,且每一正解都收敛于唯一的 2 周期解.
As an important branch of dynamical systems,difference equations always attracted widespread attention in the academic community.In recent years,the study of fuzzy difference equations attracted the attention of many scholars in this field,due to changes in methods caused by fluctuations and variations in parameters when applying difference equations to practical problems.In this study,dynamical properties of a fuzzy difference equation Xn+1=δn+Xn/Xn-1,n=0,1,2,…were investigated,where initial values X-1,X0 were positive fuzzy numbers,and parameter δn was a 2-period positive fuzzy number sequence.The research conclusion indicates that there existed a unique positive solution Xn to the fuzzy difference equation.Moreover,each positive solution converged to a unique 2-periodic solution.
