For original paper see M.D. Whitmore and J.P. Carbotte, ibid., vol.23, p.5782 (1981). In a recent paper Whitmore and Carbotte concluded that a sufficient condition for the superconducting state to be stable relative to the normal state over a finite temperature range 0TTc is that the attractive part of the effective electron-electron interaction vary over the Fermi surface. The authors show that this surprising conclusion is not true in general but results from the assumption of a separate attractive interaction
