Abstract
The density field formalism of Sherrington is used to obtain diagrammatic expansions and thus complete expressions for the quantities evaluation of the density correlation function. It is shown how these diagrammatic expansions satisfy two important sum rules to all orders. The plasmon mode is obtained in a simple fashion from these expansions.Keywords
