Isometric Representation of Lipschitz-Free Spaces over Connected Orientable Riemannian Manifolds

Functional Analysis 2025-09-18 v2

Abstract

We show that the Lipschitz-Free Space over a connected orientable nn-di\-men\-sio\-nal Riemannian manifold MM is isometrically isomorphic to a quotient of L1(M,TM)L^1(M,TM), the integrable sections of the tangent bundle TMTM, if MM is either complete or lies isometrically inside a complete manifold NN. Two functions are deemed equivalent in this quotient space if their difference has distributional divergence zero. This quotient is the pre-annihilator of the exact essentially bounded currents, and if MM is simply connected, one may replace ``exact'' with ``closed'' currents.
