We study optimal transportation with the quadratic cost function
in geodesic metric spaces satisfying suitable non-branching assumptions. We
introduce and study the notions of slope along curves and along geodesics and
we apply the latter to prove suitable generalizations of Brenier’s theorem of
existence of optimal maps.
