Formal sum of pairing diagrams

A method to summarize the connected diagrams of the master equation for the quantum fluids obtained elsewhere is used to obtain a compact expression of a set of diagrams which we call « pairing diagrams ». An integral equation is obtained. The particular interest of the method is that the set of dia...
