Abstract

We consider continuous and discrete Schr\"odinger systems with self-adjoint matrix potentials and with additional dependence on time (i.e., dynamical Schr\"odinger systems). Transformed and explicit solutions are constructed using our generalized (GBDT) version of the B\"acklund-Darboux transformation. Asymptotic expansions of these solutions in time are of interest.

Comments

In this paper, we develop further the approach to the construction of explicit solutions of dynamical systems from arXiv:1603.08709 and arXiv:1609.03451. Some results from arXiv:nlin/0311004 are actively used. In the version 2 of the paper, we consider additionally the asymptotic behaviour of the solutions in time
