我在读《陶哲轩实分析》，作者是陶哲轩,译者王昆扬.2008年11月第一版，第一次印刷.我在此添加一部分中译本印刷错误，若网友发现了另外的错误，请在评论里补充，由我代为添加.若有不当之处，敬请指正.

勘误：

3.2节，37页,公理3.9中，“不同”应该改为“不交”.

3.4节，48页，习题3.4.10中，$(\bigcap_{\alpha\in I}A_{\alpha})\bigcap(\bigcap_{\alpha\in J}A_{\alpha})=(\bigcap_{\alpha\in I\bigcap J}A_{\alpha})$应当改为$(\bigcap_{\alpha\in I}A_{\alpha})\bigcap(\bigcap_{\alpha\in J}A_{\alpha})=(\bigcap_{\alpha\in I\bigcup J}A_{\alpha})$

7.1节，130页，命题7.1.11，(e),$f:X\bigcap Y\to \mathbb{R}$应该改为$f:X\bigcup Y\to\mathbb{R}$.

7.4节，145页，习题7.4.1，$\sum_{m=0}^Ma_{f(m)}$应当改为$\sum_{m=0}^{\infty}a_{f(m)}$.

7.5节，145页，(b):如果$\alpha>1$,那么级数$\sum_{n=m}^{\infty}a_n$是条件发散的（从而是绝对发散的）。我认为最好把（从而是绝对发散的）改为（从而不是绝对收敛的），后者似乎更符合原文.

8.5节，171页，习题8.5.15中，“A的基数不小于或等于B的基数”这句话有歧义.到底是“不小于”或等于呢，还是不“小于或等于”呢？结合题目意思，应该改成“A的基数不是小于等于B的基数”.

8.5节，171页，习题8.5.20中，应当加上条件$\emptyset\not\in\Omega$.

10.4节,217页，习题10.4.1中，(b)里，$g(x)$应该为$g'(x)$.

18.2节，388页，第5行.“注意外测度对于每个集合都有定义，因为我们可以对任何非空集合取infimum”.这里译者把infimum放着没翻译，我认为翻译成“注意外测度对于每个集合都有定义，因为我们可以对任何非空集合取下确界”更好.但是译者也有他自己的理由，王先生说：

我的理解是：“下确界”只是对于有下界的集合而言，无下界的集合的infimum规定为“负无限”，它不是实数，不应称之为“下确界”。当然，如果硬规定它叫做“下确界”，也无话说。只不过说“无下界的集合的下确界是...”，不太像话。不知意下如何？

但是，我仍然认为应该把infimum译作“下确界”，这是因为陶哲轩在这里讨论的应该是广义实数，对于广义实数集合(广义实数集就是普通的实数集再添进$+\infty$和$-\infty$两个元素)来说，总是有下确界的.更详细的资料请读者见《陶哲轩实分析》中关于广义实数系的那一节，以自行判断.

18.5节，401页，引理18.5.3中，“设$\Omega$是$\mathbb{R}^n$的可测集”应该改为“设$\Omega$是$\mathbb{R}^n$的可测子集”.

18.5节，401页，推论18.5.4中，“其中$f_ j:\Omega\to \mathbb{R}^m$ 是$f$的第$j$个坐标”应该改成“其中$f_ j:\Omega\to \mathbb{R}$是$f$的第$j$个坐标”.

另外，陶哲轩本人在他的博文中也发布了英文原版的勘误，其中有一些勘误中文版可能没有改过来，请读者亲自看他的博文,可能需要FQ.

This is basically an expanded and cleaned up version of my lecture notes for Math 131A. In the US, it is available through the American Mathematical Society. It is part of a two-volume series; here is my page for Volume II. It is currently in its second edition.

There are no solution guides for this text.

p. 427: Just before Definition 15.2.4, “for some $a \in {\ bf R}$ ” should be “for some $r > 0$ “.
p. 431: In Exercise 15.2.8(e), “ $d_m (x-b)^n$ ” should be “ $d_m (x-b)^m$ .
p. 433 (proof of Theorem 15.3.1): $s_N$ in the third display and $s_0$ in the next line should be
$S_N$ and $S_0$ respectively.
p. 473: In Exercise 16.5.4, $in \hat f(n)$ should be $2\pi i n \hat f(n)$ .
p. 477: In Example 17.1.7, $x \in {\Bbb R}$ should be $c \in {\Bbb R}$ .
p. 486: In Definition 17.3.7, $1 \leq j \leq m$ should be $1 \leq j \leq n$ , and $x_0+tv$ should be $x_0+te_j$ .
p. 488: In the definition of L in the proof of Theorem 17.3.8, m should be n.
p. 492: In Exercise 17.3.1, Exercise 17.1.3 should be Exercise 17.2.1.
p. 495: In the proof of Theorem 17.5.4, $a'$ should equal $\frac{\partial}{\partial x_i} \frac{\partial}{\partial x_j} f(0)$ rather than $\frac{\partial}{\partial x_j} \frac{\partial}{\partial x_i} f(0)$ .
p. 499, proof of Lemma 17.6.6: After “ $F$ does indeed map $B(0,r)$ to itself.”, add “The same argument shows that for a sufficiently small $\varepsilon > 0$ , $F$ maps the closed ball $\overline{B(0,r-\varepsilon)}$ to itself. After “ $F$ is a strict contraction”, add “on $B(0,r)$ , and hence on the complete space $\overline{B(0,r-\varepsilon)}$ “.
p.502, proof of Theorem 17.7.2: “ $f^{-1}(y)={\tilde f}^{-1}(y+f(x_0))$ ” should be “ $f^{-1}(y)={\tilde f}^{-1}(y-f(x_0))$ “.
p. 505, Section 17.8: $(0,1)$ should be $(-1,0)$ . In the second paragraph, the function $f$ should be $g$ (for better compatibility with the discussion of the implicit function theorem).
p.508, proof of Theorem 17.8.1, “U is open and contains $(y_1, \dots,y_{n-1},0)$ ” should be “U is open and contains $(y_1, \dots,y_{n-1})$ “.
p. 515: In the display before Definition 18.2.4, $j=\in J$ should be $j \in J$ . In Definition 18.2.4, $\sum_{j=1}^\infty$ should be $\sum_{j \in J}$ .
p. 520: In Example 18.2.9, $\sum_{q\in\mathbf{Q}} m*(\mathbf{Q})$ should be $\sum_{q\in\mathbf{Q}} m*(\{q\})$ in the display.
p. 528, proof of Lemma 18.4.8: On the second line, “let $A$ be any other measurable set” should be “let $A$ be an arbitrary set (not necessarily measurable)”.
p. 545: In Corollary 19.2.11, “non-negative functions” should be “non-negative measurable functions”.
p. 555, Remark 19.5.2: x and y should be swapped in “equals 1 when $x>0$ and y=0, equals -1 when $x<0$ and y=0, and equals zero otherwise”.
