Our approach does not rely on existence and regularity results for optimal transport maps on Riemannian manifolds, but it is based on the Eulerian point of view recently introduced by Otto and Westdickenberg [SIAM J. Math. Anal., 37 (2005), pp. 1227-1255] and on the metric characterization of the gradient flows generated by the functionals in the Wasserstein space.}, doi = {10.1137/08071346X}, url = {http://hdl.handle.net/1963/3413}, author = {Sara Daneri and Giuseppe Savar{\`e}} }
