Talk:Multiplicity

[edit] Categories

[This article] is not just about multisets. It also and mostly talks about the multiplicity of roots of a function. So it should not just be in the Category:Set theory. It should be in another category as well. I guessed that it should be in Category:Numerical analysis. If I was wrong, then what other category would you put it in? JRSpriggs 06:04, 1 May 2006 (UTC)

Fair point, I was a bit rash in removing Category:Numerical analysis. My point was that multiplicity of roots is used more widely than numerical analysis. Hence, I should have put it in a more general category. I have now added Category:Mathematical analysis. Does that make sense? -- Jitse Niesen (talk) 12:51, 1 May 2006 (UTC)
Category:Mathematical analysis is the good one I think. Oleg Alexandrov (talk) 15:13, 1 May 2006 (UTC)
OK. That looks like a better category. But this raises the question of whether "Numerical analysis" should be a subcategory of "Mathematical analysis". It seems like it should be, but it is not now. JRSpriggs 07:12, 2 May 2006 (UTC)
At the moment, Category:Numerical analysis is a subcategory of Category:Analysis, which also contains Category:Mathematical analysis and Category:Musical analysis. I don't see the rationale for that, so I changed it to make num. analysis a subcategory of math. analysis as JRSpriggs suggest. -- Jitse Niesen (talk) 06:54, 4 May 2006 (UTC)

Hey guys, I appreciate the precise mathematical definition of the multiplicity of the zeros of a function, but how about a simple one line explanation that the multiplicity of a root is the number of times that root is repeated? Followed by a simple example, like the root of f(x) = (x-1)^3 is 1, with a multiplicity of 3, because it occurs 3 times.
