拓扑空间 [Topological Spaces: From Distance to Neighborhood] pdf epub mobi txt 电子书 下载
内容简介
《拓扑空间》是一部本科生学习拓扑空间的基础教程。引导读者很好的学习拓扑中有关几何的东西什么是最重要的。《拓扑空间》的内容分为三大部分,线和面、矩阵空间和拓扑空间。书中将大量的数学词汇概念囊括其中,不要求读者对简单定理或者集合知识十分了解,从而减少读者理解上的难度。收敛定理的应用在帮助读者抓住重点的同时,逐渐接触并理解拓扑的概念,书中的知识点步步逼近,前九节重在为本科生讲述矩阵空间的知识,同时也包括了大量的材料,这些将成为研究生学习的教程。

拓扑学的需要大大刺激了抽象代数学的发展,并且形成了两个新的代数学分支:同调代数与代数K理论。代数几何学从50年代以来已经完全改观。托姆的配边理论直接促使代数簇的黎曼-罗赫定理的产生,后者又促使拓扑K 理论的产生。现代代数几何学已完全使用上同调的语言,代数数论与代数群也在此基础上取得许多重大成果,例如有关不定方程整数解数目估计的韦伊猜想和莫德尔猜想的证明。范畴与函子的观念,是在概括代数拓扑的方法论时形成的。范畴论已深入数学基础、代数几何学等分支,对拓扑学本身也有影响。如拓扑斯的观念大大拓广了经典的拓扑空间观念。

拓扑空间(topological space),赋予拓扑结构的集合。如果对一个非空集合X给予适当的结构,使之能引入微积分中的极限和连续的概念,这样的结构就称为拓扑,具有拓扑结构的空间称为拓扑空间。引入拓扑结构的方法有多种,如邻域系、开集系、闭集系、闭包系、内部系等不同方法。
