  Let K be an algebraic number field. For a degree d rational morphism of
projective n-space defined over K let R denote its minimal resultant ideal. For
a fixed height function on the moduli space of dynamical systems this paper
shows that all such morphisms of bounded height and resultant are contained in
finitely many PGL(K) equivalence classes. This answers a question of Silverman
in the affirmative.
