Notes:
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–Schrödinger and Brillouin–Wigner approaches for getting Padé approximants upper and lower bounds for the ground state eigenvalue.
