Perturbative analysis of the energy-weighted sum rule of bilinear fermion operators
It is shown that the value obtained for the energy-weighted sum rule for bilinear fermionic operators using dressed one-particle propagators plus two-body random-phase approximation corrections is preserved when any higher-order correction is introduced. This is proven through the evaluation of the...

| Sumario: | It is shown that the value obtained for the energy-weighted sum rule for bilinear fermionic operators using dressed one-particle propagators plus two-body random-phase approximation corrections is preserved when any higher-order correction is introduced. This is proven through the evaluation of the corresponding perturbative diagrams. © 1991 The American Physical Society. |
