โœฆ Synopsis

Superconductivity in the electron gas is investigated in detail in the method of effective-potential expansion. After a systematic inclusion of more than 50 vertex corrections in the pairing potential, we have found that the exchange of polarization waves enhanced by the electron-hole multiple scatterings brings about superconductivity with T c in the range 10-100 K. The observed T c and the isotope-effect coefficient a for the recent high-T c oxide superconductors are explained with the use of negative p-*.

A new partitioning of the total non-relativistic energy of an N-electron system is presented. The partitioning is independent of application involving a non-variational approach to calculating the the mathematical model used to describe the system. An energy is given.
