Abstract
A new form of the BCS approximation for a pure pairing force in terms of SUq(N)-covariant fermion operators is presented. A set of quantum BCS equations is derived, as well as a q-analog to the gap equation. The quantum occupation probabilities and gap are shown to depend explicitly on the quantum parameter.
