摘要
研究了紧致度量空间中强跟踪性和强链回归点集的动力学性质,得到一些结论:(1)若f拓扑共轭于g,则连续映射f具有强跟踪性,当且仅当连续映射g具有强跟踪性;(2)连续映射g的强链回归点集是连续映射f的强链回归点集在拓扑共轭映射h下的像;(3)连续映射f^n的强链回归点集是连续映射f的强链回点集的子集;(4)移位映射σ的强链回归点集是连续映射f在它的强链回归点集上形成的逆极限空间的子集.这些结论推广和改进了目前已有文献中关于强跟踪性和强链回归点的结果.
The dynamical properties of strong shadowing property and strong chain recurrent point set are studied in the compact metric spaces and some conclusions are obtained.(1) If the map f is topologically conjugate to the map g, then f has the strong shadowing property if and only if g has the strong shadowing property;(2) The strong chain recurrent point set of the continuous map g is the image of the strong chain recurrent point set of the continuous map f under the topological conjugate map h;(3)The strong chain recurrent point set of the the continuous map f^n is a subset of the strong chain recurrent point set of the the continuous map f;(4) The strong chain recurrent point sets of the shift map σ is a subset of the inverse limit space of the continuous map f in its strong chain recurrent point sets. These conclusions generalize and improve the results of strong shadowing property and strong chain recurrent point in the existing literature.
