Collecting links to relevant websites

[GeorgeKerscher]

This group intends tocollect references to good work. This issue can serve as a mechanism for collecting those links.

We can use markdown to identify the site and its link. We can also put in a short description.

MathML and LaTex Symbols

List of LaTeX mathematical symbols

There are 13 tables that show the MathML and Latex code. This is an interesting grouping.

This site lays them out

Should this issue be in the discussions instead?

The strength of TeX is that it is extendable. It is also it's problem. There are various macro packages that define their own names for symbols. AMS LaTeX is one such package. Here is a link to a PDF that shows the AMS symbol definitions.

And in case you can't quite find what you are looking for, try The Comprehensive LaTeX Symbol List, Scott Pakin, 2024-Jan-03 which at 480+ pages lists 20323 symbols and the corresponding LaTeX commands to produce them.

Here is the Unicode Technical Note for UnicodeMath Version 3.2 from 13-Apr-23. It's very handy for understanding how UnicodeMath works, the reasoning behind it, the formal syntax, etc.

Murray Sargent contributes to the UnicodeMathML repo and has added an autocomplete listbox feature. He describes it in his Math Autocomplete blog post You can also experiment with the feature in the: UnicodeMathML Playground. In the blog post, Murray describes the feature like so:

Users of OfficeMath note that entering math symbols using a keyboard can be hard because they don't know the symbol keywords to type and/or the control words are long. To ease these problems, we create a math autocomplete listbox that displays the control words that match what the user types. The user can then use ↑↓ and Enter, mouse or touch to enter the desired symbols. For example, \in inserts ∞. You might not know that the TeX control word for ∞ is \infty, rather than \infinity, but you don’t have to know this with the autocomplete listbox.

This would have been useful to have a while ago: Symbols defined by unicode-math, Will Robertson, 2023/08/13 0.8r

Writeful.com parsed 300K LaTeX papers on arXiv to explore what LaTeX commands are used most in research writing. They published the results as These are the 100 most frequent LaTeX commands. What is useful, is that they tracked which LaTeX commands out of those top 100 were used in math mode. See the article for the full list. Here are just the math mode ones:

4. \frac (4.9%) - \frac{numerator}{denominator} produces a fraction in math environments.

5. \right (3.1%) - \right* (where * is a delimiter) must be paired with '\left*' (not necessarily
   using the same delimiter). '.' acts as a null delimiter (math mode).

6. \left (3.1%) - \left* (where * is a delimiter) must be paired with '\right*' (not necessarily
   using the same delimiter). '.' acts as a null delimiter (math mode).
