一个推广 Weinberg III讨论的refinement CFT中的类似物,待补充
现在mathjax启用braket等包还是用不了; multi line等环境未被正确识别,目前需要手动用放到math mode中

这个帖子存放一些技巧。 Markdown 和 LaTeX 的相互转换问题目前没有很好的解决方案。 在 MathJax 中启用一些包的方式为 \require{},其支持的包可见 MathJax 文档 。 关于 MathJax 的一些介绍可见 SE 的帖子。 Markdown 基础语法可见 Markdown 中文文档。 交换图的绘制, LaTeX 中我用 tikz-cd 和 tikz 在线编辑器画简单的图,MathJax 的待补充,我好像看到 Colliot 有介绍。 physics package 文档 基于 AxoDraw 的绘图界面 JaxoDraw,优点是绘图中兼容 LaTeX,缺点是 UI 太老,功能单一。 尤亦庄写的一个常见包的推荐。 放弃 Lyx 和 Typora。

我现在懂了,就是戴德金分割
不成立。现在的语法也有这样的歧义
他怎么错误了
虎哥居然还在回复,神奇
还活着!!
间歇性活着
