The research on G-shadowing property and G-periodic shadowing property(G-跟踪性和G-周期跟踪性研究)

研究了度量G-空间中G-跟踪性与G-周期跟踪性之间的动力学关系,给出了G-跟踪性和G-周期跟踪性的定义,利用等价映射和伪等价映射的性质,得到:(1)设(X,d)为紧致度量G-空间,G为可交换的紧致群,f:X→X等价,若f具有G-周期跟踪性,则PG(f)¯=CRG(f);(2)设(X,d)为紧致度量G-空间,G为紧致群,f:X→X等价,若f具有G-跟踪性且PG(f)=WG(f),则f具有G-周期跟踪性;(3)设(X,d)为紧致度量G-空间,G为可交换的紧致群,f:X→X伪等价,若f为G-扩张映射且f具有G-跟踪性,则f具有G-周期跟踪性。所得结论推广了度量空间中跟踪性和周期跟踪性的相关结论。...
