Abstract:
We derive the expressions for ψ-functions and generic solutions of lattice principal chiral equations, lattice KP hierarchy and hierarchy including lattice N-wave type equations. τ-function of n free fermions plays fundamental role in this context. Miwa's coordinates in our case appear as the lattice parameters.
