摘要
A reciprocal relation is established between the mean values of the resolvent of the Hamiltonian of a quantum mechanical system and an operator, the zeros of which give rise to the Brillouin-Wigner perturbation series. Also discussed are the consequences of this relation to the Rayleigh-Schrodinger and Brillouin-Wigner approaches for getting Pade approximants upper and lower bounds for the ground state eigenvalue.
