Title:Integrable systems on $so(4)$ related with XXX spin chains with boundaries
View PDFAbstract: We consider two-site XXX Heisenberg magnets with different boundary conditions, which are integrable systems on so(4) possessing additional cubic and quartic integrals of motion. The separated variables for these models are constructed using the Sklyanin method.
