Talk:Integral closure of an ideal

I and l indistinguishable
In the section on Structure Results, it says:

"let R be a regular ring and I an ideal generated by l elements."

On my screen (Ubuntu Linux, Firefox), the I and the l are indistinguishable. I tried putting $$l$$, but that doesn't look too pretty. Any ideas/conventions on how to resolve this? -- Hiferator (talk) 09:52, 17 March 2015 (UTC)
 * I have now replaced I and l with $I$ and $l$. -- Hiferator (talk) 21:05, 30 March 2015 (UTC)


 * I have a better idea: Avoid the use of lowercase L (regardless of font) in math notation unless absolutely necessary.2600:1700:E1C0:F340:ADCA:F710:16E3:99D0 (talk) 21:12, 25 October 2018 (UTC)

Introductory sentence needs work
The first sentence must state which set the exponent i belongs to.2600:1700:E1C0:F340:ADCA:F710:16E3:99D0 (talk) 21:09, 25 October 2018 (UTC)
