Hamiltonian structure of Sato's hierarchy of KP equations and a coadjoint orbit of a certain formal lie group
Abstract
A Hamiltonian operator related to Sato's hierarchy of KP equations is derived. The KP equation is regarded as the Hamiltonian equation of motion on a coadjoint orbit of a certain formal Lie group.
