Trace formulae for dissipative and coupled scattering systems
Jussi Behrndt, Mark M. Malamud, Hagen Neidhardt
For scattering systems consisting of a (family of) maximal dissipative extension(s) and a selfadjoint extension of a symmetric operator with finite deficiency indices, the spectral…

On the Hamiltonian structure of Hirota-Kimura discretization of the Euler top
Matteo Petrera, Yuri B. Suris
This paper deals with a remarkable integrable discretization of the so(3) Euler top introduced by Hirota and Kimura. Such a discretization leads to an explicit map, whose integrabi…

On Eisenbud's and Wigner's R-matrix: A general approach
J. Behrndt, H. Neidhardt, E. R. Racec +2
The main objective of this paper is to give a rigorous treatment of Wigner's and Eisenbud's -matrix method for scattering matrices of scattering systems consisting of two selfad…
