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。

这种方法最初要求更多的读者和他的抽象能力,但在评审者的意见,是绝对的最好方法主体。我真的不知道什么是真正的初学者在数学也能想出来但替代方法是定义事物反复在越来越通用上下文最分析文本做。

这套书给人的感觉有点不上不下。具体来说，作者（基本上是）打算避开集合论公理和数理逻辑，但又花了十几页的功夫去描述这两个东西，而且还是在避免使用符号语言的情况下，使用自然语言来说明的.......嘛，因为原文是德文，说明上应该会比这英译本的要严格一些，但是这英译本就......举个例子来讲，英译本中一会儿用英语“and”来表示逻辑符号里的"AND"，一会儿又用“and”来表示逻辑符号里的"INCLUSIVE OR"。都无语了......
