Difference between $$..., \[..., and \begin{equation*}...

I have been using \(\LaTeX\) for over 20 years now. When I write a displayed equation without numbering on a single line, I have been using $$...$$ because it was simple. I didn’t understand why some people use \[...\], because the latter takes more time to type and is not necessarily easy to read. Today I read this article and learned that $$...$$ is incorrect. From now on, I will switch to \begin{equation*}...\end{equation*} because it is easy to read and we can add equation numbering by deleting * if we change our mind.

Website updated

After spending several days, I significantly updated my website. Below is a list of main changes.

  • Previously, there was a “Research” page that I created manually. But it was tedious to list all papers in a consistent style (like journal names in bold face, coauthors in italics, etc.) so I automated it.
  • I omitted publication information except the journal name and year, because I don’t think they are very important and one can easily find by clicking the link to the published paper.
  • I searched for all my paper drafts in my computer and added slides whenever I found them.
  • I merged “Conference proceedings” with “Other publications” because I don’t see a reason to keep proceedings as a separate section given that I don’t have many.

Maybe it is not the best use of my time but I created a “Talks” page, which lists past and future talks and presentations. After spending all afternoon tweaking the code, I created something satisfactory. For now I included only talks in 2023 and 2024 but I might add past ones.
