Re: Discussions About The FormulasOkay, so the set theory thread has gotten a little out of hand. I therefore suggest that we discusss a standard that will be used. Say, for each topic, if there are two or three commonly used symbols used in that field  we pick one, and use that in each post in that particular thread. I don't know if this will be efficient, but I think it would be great for the purpose of understanding what's meant. #27 20080321 19:06:38

Re: Discussions About The FormulasIf this hasn't already been stated... Chaos is found in greatest abundance wherever order is being saught. It always defeats order, because it is better organized. #29 20120724 13:29:39
Re: Discussions About The FormulasRegarding post #11 about sets: I vote for doing just sets and not include real analysis. Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional). LaTex is like painting on many strips of paper and then stacking them to see what picture they make. #30 20120724 13:34:13
Re: Discussions About The FormulasHi noelevans; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #31 20120725 10:30:07
Re: Discussions About The FormulasComputer scientists are way ahead of the mathematicians when it comes to dealing with multisets. For example Visual Studio 12 has a list of 42 functions that operate on multisets. However there seems to be quite an analogy between LaTex/PrettyMath and VisualStudio12/PrettyMultisets. The encoding of Visual Studio 12 is much more complicated than the plain mathematical writing of multisets and their operations. That seems quite analogous to the complicated coding in LaTex vs its output. The basics of multiset theory have been known since the 1960's and maybe awhile longer. The ideas are catching on finally in the mathematical community, but have not been introduced into curricula up through at least high school.

Re: Discussions About The Formulas
Why would they introduce multisets into curriculum if they haven't done so with GF's yet?

Re: Discussions About The FormulasHi stefy! Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional). LaTex is like painting on many strips of paper and then stacking them to see what picture they make. #34 20120727 18:22:39
Re: Discussions About The FormulasGF means generating function. There is a great deal of books that dels wit/mentions them. They are mostly represented by the generatingfunctionoligy.

Re: Discussions About The FormulasUh guys, combinatorics was around way before computers. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #36 20120727 20:09:05
Re: Discussions About The FormulasMy point exactly. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #37 20120728 07:11:03
Re: Discussions About The FormulasYes indeedy! Combinatoris predates computers bunches. I probably should have said something like "Regarding awareness of multisets, the percent of CS folks that are aware is greater than the percent of mathematicians that are aware."

Your welcome. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #39 20130524 23:45:37
