Abstract

We apply a method of perturbation for the BC1BC_1 Inozemtsev model from the trigonometric model and show the holomorphy of perturbation.Consequently, the convergence of eigenvalues and eigenfuncions which are expressed as formal power series is proved. We investigate also the relationship between L2L^2 space and some finite dimensional space of elliptic functions.
