Abstract
The discrete models of the Toda and Volterra chains are being construc ted out of the continuum two-boson KP hierarchies. The main tool is th e discrete symmetry preserving the Hamiltonian structure of the contin uum models. The two-boson currents of KP hierarchy are being associate d with sites of the corresponding chain by successive actions of discr ete symmetry.
