%0 Journal Article %T Generalized KP Hierarchy for Several Variables %A Francisco J. Plaza Mart¨ªn %J Physics %D 2000 %I arXiv %X Following the techniques of M. Sato (see \cite{Sa}), a generalization of the KP hierarchy for more than one variable is proposed. An approach to the classification of solutions and a method to construct algebraic solutions is also offered. %U http://arxiv.org/abs/math/0008004v1
