Hyperbolic random walks,Although the hyperbolic r.w. defined on a regular hyperbolic planar grid satisfies an invariance principle, as we shall see, the picture radically differs from the Euclidean setting: the infinite grid is the whole space when the step is too small. We also give a radial discretization of Bochner’s subordinated hyperbolic Brownian motions.压倒 发表于 2025-3-25 10:15:08

Creation or deletion of a drift on a Brownian trajectory,ive drift can be annihilated by inserting independent excursions again according to a certain Poisson measure. We first give results in discrete time by considering the random walks as contour processes of Galton-Watson trees and then pass to the limit.Accord 发表于 2025-3-26 16:03:33
A probabilistic interpretation to the symmetries of a discrete heat equation,) using the Doob transform for Markov (jump) processes. While the first three generators of G correspond to the identity and to space and time shifts, we show that in this interpretation the fourth generator of G is associated to time dilations and is linked to a creation operator on the Poisson space.骚扰 发表于 2025-3-26 19:44:13
