Summary

The structure of the global master equation is clarified by means of a projection operator formalism which allows us to exhibit the physical meaning of the quantities that appear in the evolution of the momentum distribution. With the help of our new formulation, we give an explicit form to theH-theorem for the master equation and calculate to first order the effect of phase mixing on the propagator.

Riassunto

Si chiarisce la struttura dell’equazione maestra globale per mezzo di un formalismo che introduce un operatore di proiezione che ci permette di esporre il signiflcato fisico delle grandezze che compaiono nell’evoluzione della distribuzione degli impulsi. Con l’ausilio di questa nuova formulazione diamo una forma esplicita al teoremaH dell’equazione maestra e calcoliamo fino al primo ordine l’effetto della mescolanza delle fasi sul propagatore.
