I spent a chunk of the afternoon reading some of his papers on random evolutions, a probabilistic technique for solving partial differential equations. There appear to be a number of interesting possibilities for connecting this work to the diffusion-like weighted ensembles I have found recent interest in. In particular, he proves some theorems suggesting how "a Newtonian particle goes over to diffusion" in a manner that is suggestive of Langevin dynamics passing from Hamiltonian regimes to Brownian. Did anyone here happen to learn the technique from Reuben?</div></div>
