Similarity:

Two simple methods for approximate determination of eigenvalues and eigenvectors of linear self-adjoint operators are considered in the following two cases: (i) lower-upper bound λ 1 of the spectrum σ ( A ) of A is an isolated point of σ ( A ) ; (ii) λ 1 (not necessarily an isolated point of σ ( A ) with finite multiplicity) is an eigenvalue of A .
