Hi, I read the article about lie algebra and saw your latex compiled image: http://en.wikipedia.org/wiki/Image:Liealgebra.png which is a bit too small. could you recompile it in a bigger version? --phatsphere 19:24, 28 June 2007 (UTC)
Hi. I was wondering what all of these pages with F4 and G2 are for? They don't really add anything, and it seems they could all be covered in a single page called "F (math)" without using up potentially useful links. For instance Apple releases its processor with the names G3, G4 and G5, and these would be much more commonly asked for than a math page.
G2, F4, E6, E7 and E8 are very commonly used Lie groups in math and physics. Maybe I should rename them G2 (math) and F4 (math)? Phys
Yes please. You can use the Move this page function to do this. Still, wouldn't a single page with lie groups and various examples be more than enough? And if not, could you please state at the top of the articles that G4 is one of the common lie groups... so we know what it is. This isn't a math textbook!
Huh, there's no G4! Only a G2 and a F4! Phys
Hi there. Good work. Just one point. Avoid using Math. That is a word used only in American English. Otherwise people who don't use AE will end up changing them to the international word Maths and on such minor points as an s edit wars break out! :-( Use the full Mathematics instead which is universal.

Hello! You are adding new articles very quickly. But could you slow down a bit please? How about adding your articles to List of mathematical topics? Or list your contributions in your user page? It is hard to improve your articles if nobody really knows those articles have been created. wshun 23:52, 11 Aug 2003 (UTC)
Hi. I like your contributions to the Mathematical Physics side of Wikipedia a lot. Keep it up! -- Miguel
I'm not convinced that root system should be merged with Lie group. Root systems parametrize a lot of different things besides simple Lie groups and simple Lie algebras. Sometimes with omissions, sometimes with extra markings, they parametrize simple singularities in algebraic geometry, quivers with finitely many indecomposables, finite groups of Lie type, rigid Lagrangian singularities, regular polytopes, affine Kac-Moody Lie algebras, etc. They have an independent existence...-Michael Larsen
Was the move of Technicolor all that wise? Most people are aware of the term in association with film, not so physics. Given the large number of links to technicolor from film pages, it might have been better to leave it as it is, and add a link to the minor usage on the Technicolor page. Otherwise, you'll have to go through and edit all of the links from the films. GRAHAMUK 02:37, 14 Aug 2003 (UTC)
- I've now done this - no need to change any links, or mess about withis any longer. PLEASE!! GRAHAMUK 02:49, 14 Aug 2003 (UTC)
- Oops, I'm sorry! I didn't realize you reverted! I changed the links because you asked me to!Phys
- Yeah, sorry about that!! I saw you making the change so I figured I'd fix it in case you hadn't read this in time - oh well, never mind. I think in general disambiguationpages should be avoided unless there really are a lot of terms that come under one title. In this case, as there are only two and one is (with respect) pretty esoteric, I think this approach is the better one. I'll help revert the film links if you want GRAHAMUK
I don't understand your comment on Cayley's theorem in the adjoint representation entry. Could you elaborate or remove it? Michael Larsen
Your comment on Cayley's theorem belongs in a different article, the not yet written one about regular representations. Perhaps you would like to write it? Michael Larsen
Considering that Dual (category theory) is a single line, is there any reason it's not a part of category theory? No one is going to look for an article with this name. User:Maury Markowitz
- Well, it's on the request list and it's extendable... But if you still insist, I can merge that article. Phys 15:16, 4 Sep 2003 (UTC)
Hi, thanks for correcting my totally wrong definition on Dirac sea (but I'm quite sure that I have seen described as I wrote somewhere...). Anyway, the current version reads like a school textbook question/answer. I think a more "formal" style should be employed - no need for equations, just straightforward definitions.

Apparently you haven't read the talk page on Liouville's theorem (Hamiltonian) since the time when you created the talk page. Did you intend the differential equation in that article to be the statement of the theorem rather than a corollary of the theorem? If so, that is anything but clear from the way you wrote it. I would never have suspected it if not for your comment on the talk page, and it's still only a suspicion. Michael Hardy 03:22, 20 Sep 2003 (UTC)
- Yes, that's the theorem, not the corollary!
The page is a mess, you know.

Hello. In relatively complemented, what operation on members of a lattice are you denoting by ? I'd have interpreted it in such a way that if you're talking about the lattice of all subsets of a set, then it's the intersection of x with the complement of y. But that does not seem to be what you meant. Also, could you address the question I put on the Heyting algebra discussion page. Michael Hardy 03:34, 9 Nov 2003 (UTC)
Not quite sure I understand your latest change to von Neumann algebra. AFAICS, "commutative" already was in every place it should be, and definitely shouldn't be where you put it. Connections between noncommutative von Neumann algebras and measure spaces exist, they just aren't as simple as going from a nice measure space to L∞. So, since this is an aesthetic issue, and I really think we should mention a connection between (possibly non-commutative) von Neumann algebras and measure theory as an explanation for "noncommutative measure theory", I think I'd like to just revert your change.

Hi, I'm currently fleshing out coalgebra and was wondering if you still have the source code for ? In the left diagram, the Nabla's should be Delta's, and the whole diagram is kind of hard to read since it is so small. Also, the diagonal arrow in the right one would look better if you used anti-aliasing when converting from postscript (I assume you used TeX?) to png. Could you upload a new version if you get the chance? Cheers, AxelBoldt 16:16, 11 Aug 2004 (UTC)
- Oops, you're right. Thanks for catching that. I'll see if I can still find the source code. Phys 18:06, 11 Aug 2004 (UTC)
