Latex Notation

避免被老师卷 To avoid being criticized by professor

Mathematical Formulae

• paranthess: no need to use \left( \right) that adjust high of paranthess automatically, but should try \big \Big \bigg \Bigg to adjust mannually: \( (, \big(, \Big(, \bigg(, \Bigg( \)
• space: \, \; \quad \qquad, e.g., \min_{x} \; \max_{y} \; E[xxx]: \( 1\, 2\; 3\quad 4\qquad 5 \)
• between lines of equation, may add [5mm] or [3mm] to look pretty
• \rm in text subscript
• \mathbf{A} for matrix, \bm a for vector, \tilde \xi for random variable, \bmt \gamma for random vector
• vector zero is \bm 0

Assumption

• We further introduce the following notations to facilitate our analysis and presentation
• xxx, that is, (math formula)
• xxx, given by

Theorem

• \hfill \halmos at the end of proof
• \sc in theorem title
• \Cref is useful; if don’t use Cref, link Theorem and label with ~, e.g., Assumptions~\ref{asm1} and~\ref{asm2}; equation~\eqref{eq}
• 相似的内容(定理、定义…)要对称
• , concluding the proof
• The proof is now complete.

Citation

• What if the citation hasn’t been published?

  @article{xxx,
  title={Title.},
  author={姓1, 名1 and 姓2, 名2 and 姓3, 名3},
    year={2025},
  pages={Available at SSRN}
  }
  

  Tricks:

  • Title ends with dot .
  • Fill pages with SSRN/arxiv

Expression

• However v.s. nevertheless
• The key lies in figuring out is more academic than the key is to figuring out
• explore -> investigate
• are as follows -> are listed below
• Next we will investigate xxx. To this end, xxx / The key lies in figuring out xxx
• 从句 that 不省略 (notice, recall, ensure)，且比which formal
• the case where
• Hence, thus, consequently

Common Mistakes

• One common mistake in LaTeX is using deprecated LaTeX2.09 font commands (e.g., \bf, \it, \rm, \sf, \tt) instead of the modern LaTeX2e commands (e.g., \textbf{} or \bfseries, \textit{} or \itshape)
