Re:Polynomial recurrence

I'm not an expert in this field and as I wrote I'm far to be sure about its notability/unnotability, but "Polynomial recurrence" counts 568 entries in Google books: 1... probably are all false positive, maybe not... an AfD discussion between users more expert than me could be useful to estabilish the relevancy of these sources and the notability of this concept.

Disambiguation link notification for June 28

Hi. When you recently edited Skew and direct sums of permutations, you added a link pointing to the disambiguation page Matrices (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

Diophantine approximation

Binomial Coefficient

The definition of the binomial coefficient in terms of what it means numerically should precede discussion of binomial theorem. Reader quite possibly may only want to know what it means and have no interest in binomial theorem or Pascal Triangle.

The article at present is either deliberately designed to confuse readers or it is so poorly written that it confuses the reader as much as if it had been deliberate. Saying that the definition of the binomial coefficient, ${\binom {n}{k}}={\frac {n!}{k!\,(n-k)!}}\quad {\mbox{for }}\ 0\leq k\leq n$, where the notation, $n!$, called n factorial is defined by $n!=n(n-1)(n-2)...1$ with $0!=1$, is of less importance than Pascal's triangle and such is a very ignorant and stupid statement. Why would anybody with good sense put material on Pascal's triangle before the definition the binomial coefficient? RHB100 (talk) 17:44, 13 August 2012 (UTC)

Wikihounding

Please stop doing this IPWAI (talk) 02:45, 28 August 2012 (UTC)

I repeat my request that you please stick to constructive edits while editing Wikipedia, stop writing about stuff you do not understand and above all please stop your wikihounding. IPWAI (talk) 02:18, 30 August 2012 (UTC)

Thanks

Thanks for your comments at Talk:Ngo Bao Chau, very sensible. In ictu oculi (talk) 02:13, 3 September 2012 (UTC)

You're welcome. Many aspects of wiki-fights are bizarre, but the existence of people who rabidly support intentionally misspelling things like this when automatic redirects are so easy is new to me and particularly strange. Good luck in your efforts! --JBL (talk) 02:19, 3 September 2012 (UTC)

Well, it was new to me too. But it perhaps isn't that strange if one considers the "foreign" aspect, noting that few want to intentionally misspell the Brontë sisters. I stick in a couple of RMs of this sort every week and have run out of misspelled Czechs and Hungarians, so left with Vietnamese. First time I've done one for mathematicians, interesting sub-area of BLPs. Thanks again In ictu oculi (talk) 04:40, 3 September 2012 (UTC)

WT: WikiProject Mathematics #Square (algebra)

Your action on Square (algebra) (edit | talk | history | links | watch | logs) is disputed. Incnis Mrsi (talk) 09:06, 3 September 2012 (UTC)

Incnis Mrsi, you only just started the thread there. This isn't a dispute (yet). Furthermore this was announced back in 2011 and no-one objected as far as I can tell. Maschen (talk) 09:32, 3 September 2012 (UTC)

Union - image

Hi. You have removed image from union article. Maybe description on it's page and references will give you some counter-arguments. Regards. --Adam majewski (talk) 18:10, 9 September 2012 (UTC)

Hi Adam majewski, I see a number of mathematical comments about the given fractal on its page; can you point me to the ones you believe explain what it has to do with the concept of union (set theory)? The reason that I removed the image is the following: it's trivially true that everything is a union of the things that make it up; it seemed to me that the Julia set image illustrates this principle and nothing more, and as a result it was hard for me to see who would understand more about the concept because of the inclusion of the picture. However, as I said I am potentially open to being convinced that actually it brings something relevant to the article that isn't better explained with a simpler diagram or a sentence. Best, --JBL (talk) 18:58, 9 September 2012 (UTC)

This image is made as a union of preimages of critical orbit. No other method of drawing Julia sets uses this property. --Adam majewski (talk) 20:09, 9 September 2012 (UTC)

That's a fact about the image, and about Julia sets. It has the word "union" in it, but what does it tell me about the meaning or importance of the idea of a union? --JBL (talk) 20:40, 9 September 2012 (UTC)

Maybe animated version will be more related with infinite unions ? --Adam majewski (talk) 16:08, 10 September 2012 (UTC)
