On the construction of solutions of the Davey--Stewartson I equation using an open Toda chain

Published 27 May 2025 in nlin.SI | (2505.20786v1)

Abstract: An effective method for constructing explicit solutions to the Davey--Stewartson type integrable equations is discussed based on the use of a dressing chain. The application of the method is exemplified by the equation DS I, for which a new class of explicit solutions is constructed, containing freedom in two arbitrary functions. In this case the generalized Toda lattice corresponding to the simple Lie algebra $A_2$ is used as a dressing chain.
