A superconvergence of an FD-method for a spectral problem in the Banach space

In this work we obtaine necessary conditions for the FD-method’s super-exponential convergence with respect to eigenvectors. The mentionedmethod is targeted to solve spectral problems for linear operators in Banachspace wich can contain eigenvalues of arbitrary multiplicity.
