摘要
Consider the continuous map f : x → X and the continuous map f of K,(X) into itself induced by f, where X is a metric space and K(X) the space of all non-empty compact subsets of x endowed with the Hausdorff metric. According to the questions whether the chaoticity of f implies the chaoticity of f posed by Roman-Flores and when the chaoticity of f implies the chaoticity of f posed by Fedeli, we investigate the relations between f and f in the related dynamical properties such as transitivity, weakly mixing and mixing, etc. And by using the obtained results, we give the satisfied answers to Roman-Flores's question and Fedeli's question.
Consider the continuous map f: X → X and the continuous map (f-) of K(X)into itself induced by f, where X is a metric space and K(X) the space of all non-empty compact subsets of X endowed with the Hausdorff metric. According to the questions whether the chaoticity of f implies the chaoticity of (f-) posed by Román-Flores and when the chaoticity of f implies the chaoticity of (f-)posed by Fedeli,we investigate the relations between f and (f-) in the related dynamical properties such as transitivity, weakly mixing and mixing etc.And by using the obtained results,we give the satisfied answers to Román-Flores's question and Fedeli's question.
