List of mathematical symbols by subject seems to have been spun off of this article / translated from the German circa 2014. It's meant to have a different classification scheme so readers can choose whichever one is easier. For better or worse, the lists have ended up with more or less the same classification scheme. This article has also been converted from table to glossary format. To avoid a lot of work converting to the other article, and because it does not seem to have achieved its intended purpose, I propose merging that article into this one. -- Beland (talk) 02:24, 10 January 2021 (UTC)
I have finished to replace table entries by glossary entries. Some work is still needed for including some symbols that were lacking in the preceding version and to improve the structuration in sections. This should be much easier than with the structuration in tables, because of the modularity allowed by glossary structure.
The hard part of this restructuring work was to find the information that was lacking (or badly provided) in the previous version, namely, for each symbol
Finally, I have removed the use of Latin and Greek letters as symbols. For variables and numerical constants, these uses are the object of linked articles. There are so many uses of letters for denoting specific functions, that this can not described here, and requires a separate article, that, unfortunatly, is lacking.

I noticed this symbol when adding the Glossary to Mathematical notation (astounding that it was not already there in any incarnation). It doesn't really qualify as a mathematical symbol as defined in the opening sentence of this article but thought I should mention it "for completeness", as my high school maths teacher liked to say. --John Maynard Friedman (talk) 11:11, 14 January 2021 (UTC)
Shouldn't the last two items in the symbol column on the list NOT be identical, (both are shown as bar over X)? I believe the complex conjugate, (last entry) is bar over Z; although I was formally educated awhile back, I'd like to think I keep current. :-) Thank you for your attention in this matter, RM11
