On the Validity of Multiple Dispersion Representations
スポンサーリンク
概要
- 論文の詳細を見る
The validity of multiple dispersion representations are investigated in perturbation theory. The lowest-order vertex function is analysed as functions of two and three variables. A conjecture is proposed for the possibility of double dispersion representations. As an application of the double dispersion representation, the Bethe-Salpeter equation in ladder approximation is solved in the case of total mass zero.
