The relationship between the finite-dimensional spaces of the BC_N Inozemtsev models and the theta-type invariant spaces of the BC_N Ruijsenaars models is clarified. The degeneration of the BC_N Inozemtsev models and the correspondence of their invariant spaces are considered.16 pagesQuantum AlgebraMathematical PhysicsClassical Analysis and ODEsExactly Solvable and Integrable Systems81R12text
