  An analytic pair of dimension n and center V is a pair (V, M) where M is a
complex manifold of (complex) dimension n and V is a closed totally real
analytic submanifold of dimension n. To an analytic pair (V, M) we associate
the class of the functions u from M to a positive bounded interval which are
plurisubharmonic in M and such that u(p) = 0 for each p in V. If the class
admits a maximal function u, the triple (V, M, u) is said to be a maximal
plurisubharmonic model. After defining a pseudo-metric E(V,M) on the center V
of an analytic pair (V, M) we prove (see Theorem 4.1, Theorem 5.1) that maximal
plurisubharmonic models provide a natural generalization of the Monge-Ampere
models introduced by Lempert and Szoke in [16].
