Too many italics

[edit]

Please don't italicize indiscriminately everything that is in non-TeX mathematical notation. Variables should be italicized; digits and parentheses should not. Also, you can write "≤"; you don't need to write "<=". Michael Hardy (talk) 18:53, 18 July 2010 (UTC)[reply]

Some standard conventions

[edit]

Hello. Please see my recent edits to Capelli's identity and Jucys–Murphy element. Note that

  • In non-TeX notation, variables should be italicized, but digits and parentheses should not; and a space (often non-breakable) should precede and follow "=", "+", etc.
  • TeX should not appear in section headings because it is not visible in the article's table of contents.
  • Notice these differences:
In one case, \dots and \cdots are used; in the other case "..." is used. I put \cdots between two "+"s or between other binary operators or binary relations, and \dots between commas. I also put a "+" after \cdots. Similarly, these two are different from each other:
  • Then there's this difference:
The second one uses \text, so the letters are not italic and proper spacing is used without putting it in manually.

This stuff is in Wikipedia:Manual of Style (mathematics). Michael Hardy (talk) 03:28, 31 August 2009 (UTC)[reply]

....another item. You wrote this:

l=0,1,...r-1.

I changed it to this:

l = 0, 1, ..., r − 1.

The second one uses a minus sign rather than a hyphen, and has spaces before and after that and the "equals" sign, and also after the commas. Michael Hardy (talk) 20:52, 28 June 2010 (UTC)[reply]

Manin matrix

[edit]

Hi Alexander. I've expanded Manin matrix to turn it into a proper stub but you might want to check that I didn't add anything silly. I was careful to use only words that I understand but exotic matrix algebra isn't really my field. :-) Pichpich (talk) 19:05, 11 July 2012 (UTC)[reply]

Program for Research In Mathematics, Engineering and Science (PRIMES)

[edit]

As a frequent contributor to Wikipedia in the area of mathematics, I kindly request you to examine, and perhaps, to contribute to the discussion regarding the notability of the article on Program for Research In Mathematics, Engineering and Science (PRIMES). It has been marked for deletion, and your opinion is welcomed. Dodecahedronic (talk) 13:12, 29 September 2015 (UTC)[reply]

Hi,
You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.
