內容簡介

　　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.

作者的典型風格,因為他們承認在他們的前言,是定義數學對象和概念在最一般的方式。他們,然後通過這些定義的後果。考慮一個特定的例子,這種方法,社區的定義提齣瞭三世的連續性。1,一個函數(定義度量空間之間)是連續在x如果每個社區V f(x)存在一個這樣的社區你x f(U)包含在訴隨後,證明這是相當於兩個傳統的ε三角洲定義和連續性的情況定義在條款的收斂序列。作者也錶明連續性所以定義也同樣適用於一個賦範矢量空間(因為每個賦範矢量空間也是一個度量空間)。

這套書給人的感覺有點不上不下。具體來說，作者（基本上是）打算避開集閤論公理和數理邏輯，但又花瞭十幾頁的功夫去描述這兩個東西，而且還是在避免使用符號語言的情況下，使用自然語言來說明的.......嘛，因為原文是德文，說明上應該會比這英譯本的要嚴格一些，但是這英譯本就......舉個例子來講，英譯本中一會兒用英語“and”來錶示邏輯符號裏的"AND"，一會兒又用“and”來錶示邏輯符號裏的"INCLUSIVE OR"。都無語瞭......

阿曼和埃捨爾的分析，第一捲連同第二和第三捲,組成瞭一個令人難以置信的豐富、全麵、獨立的對於高等的分析基礎的處理。從集閤論和實數的構建,作者繼續引理、定理,定理證明的聲明和斯托剋的定理在最後一章的流形體積三世。

總的來說,它們的證明簡潔和邏輯但需要一些耐心跟隨。當做齣一個論點,作者經常引用前題一個b。c和定理x y。沒有顯式地聲明校長z,他們正在使用,即使它可能有一個名字。因此,作為一個讀者,你要麼必須願意遵循麵包屑他們提供或確保你明白為什麼他們的論證工作。這真的不是一個批評,隻是一個觀察。因為這個原因雖然,如果你打算買捲的工作,您N必須買捲N - 1。在每一捲,作者承認的序言中,他們的是太多的材料覆蓋在一個學期;事實上,至少有足夠的材料在每個捲為一個學年工作的價值。

導數不齣現,直到301頁,但當它介紹,它定義在條款的這東西到底是什麼:一個綫性近似。在大多數文本,這個觀點並不是討論直到“多元”分析覆蓋。

拓撲結構的基本概念如連通性、密實度和介紹瞭homeomorphisms早期使用作為一個基礎,證明將遠不及優雅的(和不直接)否則。例如,介值定理,證明瞭結果的連接的一個空間。一旦這是結果確定下來的普遍性,它討論瞭R。

構造函數p^2-2，然後麯綫較好的切x軸的值值更靠近根號2 ，下麵因該是p+p但是為瞭2式且不違提設可以任意取值，這個算是有跡可循的… 後麵1.21構造齣來式子纔是天馬行空數學就是這樣子，想想那些世界級的數學難題，消耗幾代人幾十年幾百年的生命去計算思考那些復雜的數學題，就顯得微不足道瞭，數學-人類精神虐待! 大傢幫我看下那道數學題怎麼做其實我建議不要刷吉米，找一本卓裏奇或者魯丁，如果覺得這些難，找一本科大版的數分都可以，個人覺得還是要有一點數學品味的吉米的很多題還是可以，我主要是想練下多偏計算的。科大的數分我看瞭一下，更難，謝謝你的建議。都差不多吧。另外，劉玉漣的鋪墊解說比較多，使初學者不感到突兀;張築生的簡潔清晰，把其他人書裏的某些分開的東西融為一體，又把某些東西拆開講，先體係後細節。因為本人理解能力並不是很強。。所以想找一本比較簡單的。。不知是華師大版的數分比較簡單呢，還是陳紀修版的簡單，或者有更好的推薦嘛？
