Non-Local Charges and their Algebra in Topological Field Theory
arXiv:hep-th/9802070 · doi:10.1016/S0370-2693(98)00933-2
Abstract
With the third order Monge-Ampère equation as an example, we show that there exists an infinite number of nonlocal conserved charges associated with the Witten-Dijkgraaf-Verlinde-Verlinde equations. A general prescription for the construction of these charges is given and the charge algebra is calculated bringing out various other interesting features associated with such systems.
