We prove a number of asymptotic results in the P(φ)2 theory in the limit when the space cut-offs are removed, in particular the behavior of El and Zt,l as t,l→∞. Such results are used to study the question of orthogonality of infinite volume Euclidean measures μ∞(λ) for varying interaction constants λ.
