Skew-selfadjoint Dirac systems with rational rectangular Weyl functions: explicit solutions of direct and inverse problems and integrable wave equations
B. Fritzsche, M. A. Kaashoek, B. Kirstein +1
In this paper we study direct and inverse problems for discrete and continuous time skew-selfadjoint Dirac systems with rectangular (possibly non-square) pseudo-exponential potenti…

Discrete skew selfadjoint canonical systems and the isotropic Heisenberg magnet model
M. A. Kaashoek, A. L. Sakhnovich
A discrete analog of a skew selfadjoint canonical (Zakharov-Shabat or AKNS) system with a pseudo-exponential potential is introduced. For the corresponding Weyl function the direct…
