Proof of String Theory Virasoro Algebra

Hi! I haven proven the Virasoro Algebra that arises in bosonic string theory. This is really a basic excercise but I got it wrong several times, so I latexed it: http://hanno-rein.de/sonstiges/24/

Include it if you think it may be useful for someone else. I don't want to add my own link.

A shorter derivation is done in 't Hooft's lectures--Lionelbrits (talk) 19:04, 3 February 2008 (UTC)

Used for ?

Can we get some information on what the Virasoro alg. is actually used for, I mean in terms of physics ? MP (talk) 17:20, 2 April 2006 (UTC)

It's quick and dirty and probably difficult to understand, but I've added some short material about the virasoro algebra in string theory. Is it what you had in mind? -lethe ^{talk +} 21:28, 2 April 2006 (UTC)

Well it's a start. Yes, it's the sort of thing I had in mind. Thanks. MP (talk) 10:25, 4 April 2006 (UTC)

I don't want to be an ass, but what you describe as a "lowest weight rep" is in fact a "highest weight rep" (mathematics). Physically, it has the lowest energy, but it's still called a highest weight rep.

This is true. Myrkkyhammas (talk) 08:16, 28 February 2009 (UTC)

Real elements ?

The statement that "L_n+L_(-n) and c are real elements" should be explained.

Fuchs v.s. Fuks

Dimitry spells his name "Fuchs". I changed the three appearances of his name to reflect this. I couldn't find a copy of "The cohomology of the Lie algebra of vector fields in a circle" to verify it was not published under the name "Fuks". — Preceding unsigned comment added by Aaport (talk • contribs) 20:52, 14 February 2011 (UTC)
