Lower-bound estimates for the ground-state energy of the helium atom are determined using nonlinear programming techniques. Optimized lower bounds are determined for single-particle, radially correlated, and general correlated wave functions. The local nature of the method employed makes it a very s
## Abstract In this paper, finite dimensional approximations for the electronic ground state solution of a molecular system are studied in the Thomas–Fermi–von Weizsäcker type setting. The convergence of the finite dimensional approximations obtained by a Galerkin discretization of the nonlinear ei
