Thoughts take shape here.


Before You Dive In

1. For personal study and reference only. Please do not redistribute without permission.
2. Tags such as “@PDF” indicate the available file formats. To request access to password-protected files or the source code of certain notes, please contact me.
3. Language labels appear before each title: “[CN]” for Chinese, “[EN]” for English and “[BI]” for bilingual content. Status labels include “Finalized” for completed notes, “Ongoing” for notes still being updated, and “Pending” for planned notes. Chapter- or section-level updates are usually posted on my WeChat Official Account.
4. As the notes are revised and updated, earlier versions may be removed from this page.


My Custom Templates

mxbook (@PDF demo V260610@TEX), mxslide (V260524@ODP)

These are templates I designed for book-style notes and slide presentations: mxbook is a LaTeX book template, while mxslide is a custom TeXSlide style. New versions are uploaded only after substantial revisions.

I highly recommend TeXSlide for polished LaTeX presentations. By integrating seamlessly with your local LaTeX engine, it delivers accurate real-time rendering of complex formulas and charts, leaving you free to focus on the ideas, structure, and content.


Selected Notes

I have recorded some explanatory videos on foundational courses in mathematics, economics, and actuarial science, based on my own notes and several classic textbooks. Click here to view them.
