In 2006, Tom Kurtz and I co-authored a book on a Hamilton-Jacobi approach to the Large deviation theory for Markov processes. An important step is to prove the uniqueness of a limiting Hamilton-Jacobi PDE. I will outline this approach in the beginning part of this talk. Then I give a few examples, including one open problem in statistical mechanics. A characteristic difficulty of the open problem is an invariance relation.

Optimal mass transport (OMT) provides a natural geometry for interpolating distributions (displacement interpolation) and modeling flows. As such it has been the cornerstone of many recent developments in physics, probability theory, image processing, time-series analysis, and systems and control. An alternative framework, rooted in statistical mechanics and large deviations, is that of Schrödinger bridges (entropic interpolation) which can in fact be seen as a stochastic regularization of OMT.
