In this paper we study complete vertical graphs of constant mean curvature
in the Hyperbolic and Steady State spaces. We first derive suitable
formulas for the Laplacians of the height function and of a support-like function
naturally attached to the graph; then, under appropriate restrictions on the values
of the mean curvature and the growth of the height function, we obtain necessary
conditions for the existence of such a graph. In the two-dimensional case we
apply this analytical framework to state and prove Bernstein-type results in each of
these ambient spaces.
