Ruijsenaars spectral transform

N. Belousov, S. Khoroshkin

Spectral decomposition with respect to the wave functions of Ruijsenaars hyperbolic system defines an integral transform, which generalizes classical Fourier integral. For a certai…

Reflection operator and hypergeometry I: spin chain

P. Antonenko, N. Belousov, S. Derkachov +1

In this work we consider open spin chain, mainly the simplest case of one particle. Eigenfunctions of the model can be constructed using the so-called reflectio…
