چکیده

In this paper, we will show that the cost − cosh ◦dHn is a regular cost, meaning that minimizing this cost on hyperbolic space yields a smooth optimal map between two given distributions of mass which satisfies suitable hypotheses. We show this by proving this cost satisfies Ma-Trudinger-Wang’s conditions and by investigating notions of convexity under this cost.

The intrinsic dynamics of optimal transport∗

The question of which costs admit unique optimizers in the Monge-Kantorovich problem of optimal transportation between arbitrary probability densities is investigated. For smooth costs and densities on compact manifolds, the only known examples for which the optimal solution is always unique require at least one of the two underlying spaces to be homeomorphic to a sphere. We introduce a (multiv...

A Solvable Stochastic Control Problem in Real Hyperbolic Three Space II

A stochastic optimal control problem is formulatedand explicitly solved in a real hyperbolic space of dimension three. The problem is to control Brownian motion in this noncompact symmetric space by a drift vector field so that the controlled diffusion remains close to the origin. This problem modifies a previous explicitly solvable control problem of the author to provide a more enhanced formu...

1 0 Ju n 20 16 REMARKS ON CURVATURE IN THE TRANSPORTATION METRIC

According to a classical result of E. Calabi any hyperbolic affine hypersphere endowed with its natural Hessian metric has a non-positive Ricci tensor. The affine hyperspheres can be described as the level sets of solutions to the “hyperbolic” toric Kähler-Einstein equation e = detDΦ on proper convex cones. We prove a generalization of this theorem showing that for every Φ solving this equation...

On the Delta-shock Front Problem

In this paper the δ-shock front problem is studied. For some classes of hyperbolic systems of conservation laws (in several space dimension, too) we introduce the definitions of a δ-shock wave type solution relevant to the front problem. The Rankine–Hugoniot conditions for δ-shocks are analyzed from both geometrical and physical points of view. δ-Shock balance relations connected with area and ...

Continuous-Flow Graph Transportation Distances

Optimal transportation distances are valuable for comparing and analyzing probability distributions, but larger-scale computational techniques for the theoretically favorable quadratic case are limited to smooth domains or regularized approximations. Motivated by fluid flowbased transportation on Rn, however, this paper introduces an alternative definition of optimal transportation between dist...
