陶哲轩博客写数学问题时，通常先把对象定义清楚，再给直觉、反例和证明轮廓。把「WordPress LaTeX bug collection drive」改写成可阅读的中文笔记，重点是：问题在问什么、已知到哪一步、下一步最容易走偏在哪。原站广告、分享条和导航已去掉。

— The brackets bug —

By and large, I am quite happy with the LaTeX support provided by wordpress, which hosts my blog (and many other maths blogs out there); it is certainly superior to the maths support of most other off-the-shelf blog formats I have looked at. But it does have some annoying bugs and quirks; a lot of perfectly good LaTeX gets converted into “Formula does not parse”.

It occurred to me that maybe one should start a page that collects all the known bugs so that they can be sent at some point to the wordpress programmers to fix. So, here is my initial list of known bugs: any other wordpress users out there are very welcome to contribute their own.

— The trivial LaTeX bug —

Convention: I will drop the “latex” when I want to show a fragment of LaTeX source code without making it compile, e.g.

$\int_{-\infty}^\infty e^{-\pi x^2}\ dx = 1$ becomes .

— The double spacing bug —

[ Update , Feb 14: The bugs have now been fixed; see comments below.]

This one comes up quite a lot: any LaTeX string that begins with a bracket [ automatically does not parse. For instance,

— The nested brackets bug —

A workaround here is to put some filler in front of the bracket, e.g.

When applying LaTeX to a single character, the parser sometimes gives up:

阅读和落地时建议先做的 5 件事

1. 用自己的语言重写定义和结论，不看原文能不能说清对象是什么。
2. 找一个最小反例或边界情形，确认假设少一条会怎样。
3. 把证明拆成可独立检验的引理，每步只保留一个新想法。
4. 若涉及计算或形式化，先写可复现的小例子，再谈一般情形。
5. 记下尚未解决的缺口：缺估计、缺构造，还是缺正确的范畴。

和智能体、形式化工具怎么接

龙虾PRO做 OpenClaw 落地时，数学笔记最有用的部分往往是「可检验的步骤」：定义、反例、引理边界。智能体适合帮忙展开计算和检索，不适合代替你决定哪条假设能扔。

本文侧重全链路风控方法论。落地时请用自身业务单据做回放验证，不要把示例阈值直接当生产策略。 相关：风控体检 · 方案资源
