摘要：

We propose a new method to obtain lower bounds on the ground-state energy of an N-body hamiltonian considered as a sum of two-body hamiltonians. When this is applied to a system of non-relativistic graviting bosons, the difference between variational upper bounds and the new lower bound never exceeds 17% or, if we accept to take a refined numerical calculation for the three-body case as input, 11%. As an illustration, the variational upper bound is used to obtain a semi-relativistic upper limit on the mass of a miniboson star. © 1990.
