摘要
研究部分拓扑弱混合性与初值敏感依赖的关系,给出弱混合子集的等价条件。若动力系统满足下述条件:1.A是(X,f)的拓扑弱混合子集;2.X-A是有限集,且f(X-A)X-A;3.=X,则f对初值敏感依赖。在一定的条件下,部分拓扑弱混合性的动力系统是初值敏感依赖的。
Investigate the relationship between partly topological weak mixing and sensitive dependence on initial conditions. Give equivalent condition of a weakly mixing subset. If dynamical system(X, f)meet three conditions: (1)A is a weakly mixing subset of (X, f) ; (2)X-A is a finite set, andf(X-A) X-A; and (3)p(f) =X, then it is sensitive dependence on initial conditions. Under uncertain conditions, the dynamical system of partly topological weak mixing is sensitive dependence on initial conditions.
