拓撲空間 [Topological Spaces: From Distance to Neighborhood] pdf epub mobi txt 電子書 下載 2024
內容簡介
《拓撲空間》是一部本科生學習拓撲空間的基礎教程。引導讀者很好的學習拓撲中有關幾何的東西什麼是最重要的。《拓撲空間》的內容分為三大部分,綫和麵、矩陣空間和拓撲空間。書中將大量的數學詞匯概念囊括其中,不要求讀者對簡單定理或者集閤知識十分瞭解,從而減少讀者理解上的難度。收斂定理的應用在幫助讀者抓住重點的同時,逐漸接觸並理解拓撲的概念,書中的知識點步步逼近,前九節重在為本科生講述矩陣空間的知識,同時也包括瞭大量的材料,這些將成為研究生學習的教程。

空間中一條自身不相交的封閉麯綫,會發生打結現象。要問一個結能否解開(即能否變形成平放的圓圈),或者問兩個結能否互變,並且不隻做個模型試試,還要給齣證明,那就遠不是件容易的事瞭(見紐結理論)。

注意到如能在X中給齣度量則自然在X中給齣拓撲(由度量決定的開集)。
