Talk:Restriction (mathematics)

Why sheaf theory?
Why is sheaf theory brought into play? What is covered here is the entirely elementary concept of restricting the domain of a function or relation to a subset of a wider domain, for the case of functions also treated in a more accessible way at Function (mathematics), and for relations at Binary relation. --Lambiam 13:51, 21 March 2011 (UTC)

Restricting with respect to the second argument of a function of two arguments
How to typeset that in readable notation? Say, f(x,y), restrict y. Evgeni Sergeev (talk) 06:13, 22 November 2013 (UTC)

Math rating
I am upgrading the rating to a C following the description of a C article: "Useful to many readers. A reader would feel they generally understood the basics the topic, but there are noticeable gaps in the material presented. There may be questionable or irrelevant material or the material may not be organized in a way that makes the subject easy to understand. Will be of little or no use to a serious student or researcher."

Could use more references and better organization for a higher rating. Feel free to change if you disagree.Brirush (talk) 17:25, 13 October 2014 (UTC)


 * Nice work on expanding this unsourced stub into a C-class article! I agree that this is a solid C-class article. The expansion is about fourfold in the last 4 days, almost enough for a Did you know nomination. --Mark viking (talk) 18:44, 13 October 2014 (UTC)
