The class of uniformly smooth hyperbolic spaces was recently introduced by
Pinto as a common generalization of both CAT(0) spaces and uniformly smooth
Banach spaces, in a way that Reich's theorem on resolvent convergence could
still be proven. We define products of such spaces, showing that they are
reasonably well-behaved. In this manner, we provide the first example of a
space for which Reich's theorem holds and which is neither a CAT(0) space, nor
a convex subset of a normed space.
