Abstract
Superconductivity in a metal with a charge-density-wave (CDW) broken symmetry is investigated within the framework of Bardeen-Cooper-Schrieffer theory. The anisotropic gap equation for (k) is solved analytically. We find that whenever k approaches a CDW energy gap, (k) undergoes a sudden increase. This behavior is the opposite of that found for a spin-density-wave (SDW) broken symmetry, for which (k) decreases precipitously as k approaches a SDW energy gap.
