内容简介

　　As with the first, the second volume contains substantially more material than can be covered in a one-semester course. Such courses may omit many beautiful and well-grounded applications which connect broadly to many areas of mathematics.We of course hope that students will pursue this material independently; teachers may find it useful for undergraduate seminars.

阿曼和埃舍尔的分析，第一卷连同第二和第三卷,组成了一个令人难以置信的丰富、全面、独立的对于高等的分析基础的处理。从集合论和实数的构建,作者继续引理、定理,定理证明的声明和斯托克的定理在最后一章的流形体积三世。

总的来说,它们的证明简洁和逻辑但需要一些耐心跟随。当做出一个论点,作者经常引用前题一个b。c和定理x y。没有显式地声明校长z,他们正在使用,即使它可能有一个名字。因此,作为一个读者,你要么必须愿意遵循面包屑他们提供或确保你明白为什么他们的论证工作。这真的不是一个批评,只是一个观察。因为这个原因虽然,如果你打算买卷的工作,您N必须买卷N - 1。在每一卷,作者承认的序言中,他们的是太多的材料覆盖在一个学期;事实上,至少有足够的材料在每个卷为一个学年工作的价值。

作者的典型风格,因为他们承认在他们的前言,是定义数学对象和概念在最一般的方式。他们,然后通过这些定义的后果。考虑一个特定的例子,这种方法,社区的定义提出了三世的连续性。1,一个函数(定义度量空间之间)是连续在x如果每个社区V f(x)存在一个这样的社区你x f(U)包含在诉随后,证明这是相当于两个传统的ε三角洲定义和连续性的情况定义在条款的收敛序列。作者也表明连续性所以定义也同样适用于一个赋范矢量空间(因为每个赋范矢量空间也是一个度量空间)。

拓扑结构的基本概念如连通性、密实度和介绍了homeomorphisms早期使用作为一个基础,证明将远不及优雅的(和不直接)否则。例如,介值定理,证明了结果的连接的一个空间。一旦这是结果确定下来的普遍性,它讨论了R。
