Our main contribution is a homogenisation result that describes the effective behaviour of the discrete problems in terms of a continuous optimal transport problem. The effective energy density can be explicitly expressed in terms of a cell formula, which is a finite-dimensional convex programming problem that depends non-trivially on the local geometry of the discrete graph and the discrete energy density. Our homogenisation result is derived from a Γ\r\n-convergence result for action functionals on curves of measures, which we prove under very mild growth conditions on the energy density. We investigate the cell formula in several cases of interest, including finite-volume discretisations of the Wasserstein distance, where non-trivial limiting behaviour occurs."}],"publication_status":"published","publication_identifier":{"issn":["0944-2669"],"eissn":["1432-0835"]},"file_date_updated":"2023-10-04T11:34:10Z","month":"04","arxiv":1,"department":[{"_id":"JaMa"}],"file":[{"date_updated":"2023-10-04T11:34:10Z","creator":"dernst","file_size":1240995,"date_created":"2023-10-04T11:34:10Z","file_id":"14393","content_type":"application/pdf","access_level":"open_access","file_name":"2023_CalculusEquations_Gladbach.pdf","success":1,"checksum":"359bee38d94b7e0aa73925063cb8884d","relation":"main_file"}],"article_number":"143","oa":1,"language":[{"iso":"eng"}],"issue":"5","citation":{"ista":"Gladbach P, Kopfer E, Maas J, Portinale L. 2023.

These are identified, as is well known, in the case of the variance in terms of an appropriate Hilbertian norm; and in the case of the relative entropy, in terms of a Dirichlet form which morphs into a version of the familiar Fisher information under conditions of detailed balance. Here we obtain trajectorial versions of these results, valid along almost every path of the random motion and most transparent in the backwards direction of time. Martingale arguments and time reversal play crucial roles, as in the recent work of Karatzas, Schachermayer and Tschiderer for conservative diffusions. Extensions are developed to general “convex divergences” and to countable state-spaces. The steepest descent and gradient flow properties for the variance, the relative entropy, and appropriate generalizations, are studied along with their respective geometries under conditions of detailed balance, leading to a very direct proof for the HWI inequality of Otto and Villani in the present context."}],"date_created":"2021-09-19T08:53:19Z","article_type":"original","volume":21,"title":"Trajectorial dissipation and gradient flow for the relative entropy in Markov chains","oa_version":"Preprint","day":"04","author":[{"last_name":"Karatzas","full_name":"Karatzas, Ioannis","first_name":"Ioannis"},{"full_name":"Maas, Jan","id":"4C5696CE-F248-11E8-B48F-1D18A9856A87","last_name":"Maas","first_name":"Jan","orcid":"0000-0002-0845-1338"},{"last_name":"Schachermayer","full_name":"Schachermayer, Walter","first_name":"Walter"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","citation":{"ama":"Karatzas I, Maas J, Schachermayer W.

However, we show that the corresponding lower bound may fail in general, even on certain one-dimensional and symmetric two-dimensional meshes. In addition, we show that the asymptotic lower bound holds under an isotropy assumption on the mesh, which turns out to be essentially necessary.

Such metrics appear naturally in discretisations of -gradient flow formulations for dissipative PDE.

In this paper we prove that, in a 1-dimensional periodic setting, discrete transport metrics converge to a limiting transport metric with a non-trivial effective mobility. This mobility depends sensitively on the geometry of the mesh and on the non-local mobility at the discrete level.

This extension of the original transport model enables local density modulations, which is a desirable feature in applications such as image warping and blending. A key advantage of the use of a functional with linear growth in space is that it allows for singular sources and sinks, which can be supported on points or lines. On a technical level, the L2-norm in time ensures a disintegration of the source in time, which we use to obtain the well-posedness of the model and the existence of geodesic paths. The numerical discretization is based on the proximal splitting approach [18] and selected numerical test cases show the potential of the proposed approach.

For a pair of given input images geodesic paths in the space of images are defined as minimizers of a resulting path energy. To this end, the underlying Riemannian metric measures the rate of transport cost and the rate of viscous dissipation. Furthermore, the model is capable to deal with strongly varying image contrast and explicitly allows for sources and sinks in the transport equations which are incorporated in the metric related to the metamorphosis approach by Trouvé and Younes. In the non-viscous case with source term existence of geodesic paths is proven in the space of measures. The proposed model is explored on the range from merely optimal transport to strongly dissipative dynamics. For this model a robust and effective variational time discretization of geodesic paths is proposed. This requires to minimize a discrete path energy consisting of a sum of consecutive image matching functionals. These functionals are defined on corresponding pairs of intensity functions and on associated pairwise matching deformations. Existence of time discrete geodesics is demonstrated. Furthermore, a finite element implementation is proposed and applied to instructive test cases and to real images. In the non-viscous case this is compared to the algorithm proposed by Benamou and Brenier including a discretization of the source term.

In one dimension, it has been shown by Adams, Dirr, Peletier and Zimmer that this functional is asymptotically equivalent (in the sense of Γ-convergence) to the Jordan-Kinderlehrer-Otto functional arising in the Wasserstein gradient flow structure of the Fokker-Planck equation. In higher dimensions, part of this statement (the lower bound) has been recently proved by Duong, Laschos and Renger, but the upper bound remained open, since the proof of Duong et al relies on regularity properties of optimal transport maps that are restricted to one dimension. In this note we present a new proof of the upper bound, thereby generalising the result of Adams et al to arbitrary dimensions.\r\n","lang":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":" 20","volume":20,"date_created":"2018-12-11T11:52:29Z","author":[{"first_name":"Matthias","full_name":"Erbar, Matthias","last_name":"Erbar"},{"last_name":"Maas","full_name":"Maas, Jan","id":"4C5696CE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0845-1338","first_name":"Jan"},{"first_name":"Michiel","last_name":"Renger","full_name":"Renger, Michiel"}],"scopus_import":1,"day":"29","oa_version":"Published Version","title":"From large deviations to Wasserstein gradient flows in multiple dimensions","citation":{"ista":"Erbar M, Maas J, Renger M. 2015.

A solution theory for this class of equations has been developed recently in Probability Theory Related Fields by Hairer and Weber. The key idea was to use the theory of controlled rough paths to give definitions of weak/mild solutions and to set up a Picard iteration argument. In this article the limiting behavior of a rather large class of (spatial) approximations to these equations is studied. These approximations are shown to converge and convergence rates are given, but the limit may depend on the particular choice of approximation. This effect is a spatial analogue to the Itô-Stratonovich correction in the theory of stochastic ordinary differential equations, where it is well known that different approximation schemes may converge to different solutions.","lang":"eng"}],"volume":67,"_id":"2131","date_updated":"2021-01-12T06:55:30Z","date_created":"2018-12-11T11:55:53Z","type":"journal_article","day":"01","doi":"10.1002/cpa.21495","author":[{"full_name":"Hairer, Martin M","last_name":"Hairer","first_name":"Martin"},{"orcid":"0000-0002-0845-1338","first_name":"Jan","last_name":"Maas","full_name":"Jan Maas","id":"4C5696CE-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Weber, Hendrik","last_name":"Weber","first_name":"Hendrik"}],"title":"Approximating Rough Stochastic PDEs","publisher":"Wiley-Blackwell","citation":{"ista":"Hairer M, Maas J, Weber H. 2014.
