Isometric approximations from finite dimensional space into l 1空間的等距逼近問題
Finite dimensional space 有限維空間
In addition , the paper will analyze the existence condition for nonwandering semigroup by the methods of topological dynamical system . from the mature results of finite dimensional space , such as the topological mixing , we discuss any other methods to solve the problems of infinite dimensional space , so as to provide the similar methods for the similar work 另一方面,本文將結(jié)合微分動力系統(tǒng)和拓撲動力系統(tǒng)的研究方法,主要從微分動力系統(tǒng)的角度,從根本上分析非游蕩算子半群存在的條件,并結(jié)合與此密切相關的有限維空間的一些成熟的理論,如拓撲動力系統(tǒng)中的拓撲混合性等,從不同角度試圖解決無窮維空間的結(jié)論。
