Abstract:
Simple treatments are presented for evaluating the many-point ring diagrams in the degenerate case, where the electron momentum vectors relative to the initial one depend linearly. It is noted that in the structural expansion of the thermodynamical potential of metals, all of the higher order diagrams than the fourth fall into the degenerate case. The present results are more tractable and comprehensive than the previous one by Brovman and Kholas.
