Infinite volume asymptotics inP(ø)2 field theory

We prove a number of asymptotic results in theP(φ)2 theory in the limit when the space cut-offs are removed, in particular the behavior ofEl andZt,l ast,l→∞. Such results are used to study the question of orthogonality of infinite volume Euclidean measuresμ∞(λ) for varying interaction constants λ.
