Abstract: | In the present note we outline a truncation scheme for configuration space ofN-electron systems in definite spin statesS for Hubbard Hamiltonian with first neighbour transfer terms. For this sparse matrix we find that the present truncation scheme yields reasonably good ground and first excited states with very limited space being used. |
