Abelian Current Algebra and the Virasoro Algebra on the Lattice
arXiv:hep-th/9307048 · doi:10.1016/0370-2693(93)91618-W
Abstract
We describe how a natural lattice analogue of the abelian current algebra combined with free discrete time dynamics gives rise to the lattice Virasoro algebra and corresponding hierarchy of conservation laws.
