Abstract

We give a proof for a fact that for any Weil height hX with respect to an ample divisor on a projective variety X, any dynamical system F of rational self-maps on X, and any ε>0, there is a positive constant C=C(X, hX, f, ε) such that ∑f ∈ Fn h+X(f(P)) ≤ C. kn.(δF + ε)n . h+X(P) for all points P whose F-orbit is well defined, with δF being a dynamical degree associated with a system of several maps, defined by the author in the previous paper mentioned above.
