In this article, the authors considered space inhomogeneous random motions of particles on the line and in the plane, and the changes of the movement direction are driven by a Poisson process.
Abstract
Space inhomogeneous random motions of particles on the line and in the plane are considered in the paper. The changes of the movement direction are driven by a Poisson process. The particles are assumed to move according to a finite velocity field that depends on a spatial argument. The explicit distribution of particles is obtained in the paper for the case of dimension 1 in terms of characteristics of the governing equations. In the case of dimension 2, the distribution is obtained if a rectifying diffeomorphism exists.

Branching random motions, nonlinear hyperbolic systems and traveling waves

TL;DR: In this paper, a branching random motion on a line, with abrupt changes of direction, is studied, and the convergence of solutions with Heaviside terminal data to the traveling waves is discussed.

Models of dispersal in biological systems

TL;DR: Two stochastic processes that model the major modes of dispersal that are observed in nature are introduced, and explicit expressions for the mean squared displacement and other experimentally observable quantities are derived.
