Abstract
An equation for the critical temperature of dilute superconducting alloys is derived by the method of functional integrals, considering that transition-metal impurities are represented by the Hamiltonian of Anderson. The results obtained in the static approximation and symmetric case are shown to describe the magnetic-nonmagnetic transition observed in alloys with Ce impurities.Keywords
