On the intrinsic group of a kac algebra
WebLet A be any Kac-Moody algebra all of whose real roots have norm 2.(Everything here can be generalized to all Kac-Moody algebras but becomes a lot more complicated, so for simplicity I will mostly just describe this case.) A is defined by certain generators and relations depending on the Cartan matrix of A, and one of the most important ...

Webis a Lie algebra product on V/DV, where DV is the image of V under a certain derivation D. This Lie algebra V/DV contains the Kac-Moody algebra A as a subalgebra but is always far larger than A. To reduce V/DV to a smaller subalgebra, we will use the Virasoro algebra. This is spanned by the operators ci and 1, where c is a certain element of V.
