Representations of Virasoro-Heisenberg Algebras and Virasoro-Toroidal Algebras

Canadian Journal of Mathematics, 1999
AbstractVirasoro-toroidal algebras, , are semi-direct products of toroidal algebras and the Virasoro algebra. The toroidal algebras are, in turn, multi-loop versions of affine Kac-Moody algebras. Let Γ be an extension of a simply laced lattice by a hyperbolic lattice of rank two. There is a Fock space V(Γ) corresponding to Γ with a decomposition as a

PRESENTATION FOR THE VIRASORO ALGEBRA

International Journal of Algebra and Computation, 1995
It is proved that the Virasoro algebra can be constructed starting with only two generators L3, L−2 subjected to 5 relations without neither introducing a central element c (charge) nor assuming any symmetry relation. Our proof is supported by substantial symbolic computations in REDUCE.
