Abstract
The nature of the ground-state broken symmetry in a one-dimensional half-filled band with arbitrarily long-range Coulomb interactions between electrons is shown to be precisely given by two simple inequalities involving the Coulomb parameters. It is further shown that non- periodicity may occur if the first of these inequalities is violated.
