Mean first escape times of Brownian motion on asymptotically hyperbolic and gas giant metric surfaces
Jesse Gell-Redman, Emanuel József Godfried, Justin Tzou +1
This paper deals with the mean first escape time of Brownian motion on asymptotically hyperbolic and gas giant surfaces. We show that for a boundary defining function , the mea…

The Klein-Gordon equation on asymptotically Minkowski spacetimes: the Feynman propagator
Dean Baskin, Moritz Doll, Jesse Gell-Redman
We develop a theory of Feynman propagators for the massive Klein--Gordon equation with asymptotically static perturbations. Building on our previous work on the causal propagators,…

The Klein-Gordon equation on asymptotically Minkowski spacetimes: causal propagators
Dean Baskin, Moritz Doll, Jesse Gell-Redman
We construct the causal (forward/backward) propagators for the massive Klein-Gordon equation perturbed by a first order operator which decays in space but not necessarily in time.…
