โœฆ Synopsis

For self-adjoint operators having isolated cisenvalucs of finite multiplicity in the lower part of their spectrum NC prove a convergence theorem for Rayleigh-Ritz approximations under weak complctencss assumptions on the basis functions. The result is applied to CLcalculations for molecules.
