The t-J model is analyzed in the context of the path-integral formalism. The starting point is the first-order Lagrangian formulation written in terms of the Hubbard operators recently developed. Subsequently, by using functional techniques the correlation generating functional is constructed in ter

We recently proposed (parts I and II' of this series of publications) a new method of infinite subsummation in the Mlrller-Plesset perturbation series with the objective of "effecting wnvergenee of otherwise divergent series". In the present work we undertake to study the importance of a shift of un
