Solitonic combinations, commuting nonselfadjoint operators, and applications
Abstract
In this paper, applications of the connection between the soliton theory and the commuting nonselfadjoint operator theory, established by M.S. Liv\v{s}ic and Y. Avishai, are considered. An approach to the inverse scattering problem and to the wave equations is presented, based on the Liv\v{s}ic operator colligation theory (or vessel theory) in the case of commuting bounded nonselfadjoint operators in a Hilbert space, when one of the operators belongs to a larger class of nondissipative operators with asymptotics of the corresponding nondissipative curves. The generalized Gelfand-Levitan-Marchenko equation of the cases of different differential equations (the Korteweg-de Vries equation, the Schr\"{o}dinger equation, the Sine-Gordon equation, the Davey-Stewartson equation) are derived. Relations between the wave equations of the input and the output of the generalized open systems, corresponding to the Schr\"{o}dinger equation and the Korteweg-de Vries equation, are obtained. In these two cases, differential equations (the Sturm-Liouville equation and the 3-dimensional differential equation), satisfied by the components of the input and the output of the corresponding generalized open systems, are derived.
