“…The method of invariant manifolds is one of the most common methods for constructing solutions to nonlinear equations (see, for example, [8]). As alternative approaches to the problem of constructing solutions to nonlinear equations, we should mention the method of conditional symmetries [6,7,9], the Puiseux series method [10], the method of asymptotic expansions [11] and the method of finite-gap integration [12][13][14][15][16][17][18][19][20][21].…”

“…The finite-gape integration method is effectively applied to nonlinear integrable chains as well. Finite-gap solutions of nonlinear Volterra and Toda lattices, as well as the relativistic Toda lattice, were investigated in a number of works [8,[10][11][12][15][16][17][18][19]. In them one can find explicit formulas for the solutions of these chains in terms of the Riemann theta functions, as well as analogues of Dubrovin's equations (1.3), which determine the dynamics in time t. As far as the authors know, analogs of the Dubrovin equations describing the dynamics in the spatial variable n ∈ Z have not been presented before.…”
