On Coset Reductions of KP Hierarchies
arXiv:hep-th/9409126 · doi:10.1007/BF02066658
Abstract
In this talk the class of multi-fields reductions of the KP and super-KP hierarchies (leading to non-purely differential Lax operators) is revisited from the point of view of coset construction. This means in particular that all the hamiltonian densities of the infinite tower belong to a coset algebra of a given Poisson brackets structure.
