Summary

THE PROPERTIES OF THE SUPERCONDUCTING STATE IN A METAL WITH SINGULARITIES OF SPECTRUM ON THE FERMI SURFACE ARE CONSIDERED FROMTHE STANDPOINT OF SYMMETRY. THE DEPENDENCIES OF THE ELECTRON SPECIFIC HEAT OF THE SUPERCONDUCTOR ON THE TEMPERATURE ARE OBTAINED FOR THE TOPOLOGICAL TRANSITION OF THE FERMI SURFACE. IT IS ALSO SHOWN HOW DEGENERACY OF THE ELECTRON SPECTRUM OF THE FERMI SURFACE ALTERS THE ZERO PATTERN OF THE ENERGY GAP. THE POSSIBLE CONNECTION BETWEEN THESE PHENOMENA AND SUPERCONDUCTIVITY IN METAL OXIDES IS DISCUSSED.
