WebAbstract: For general β ľ 1, we consider Dyson Brownian motion at equilibrium and prove convergence of the extremal particles to an ensemble of continuous sample paths in the limit N Ñ 8. For each fixed time, this ensemble is distributed as the Airyβ random point field. We prove that the increments of the limiting process are locally Brownian. When β ą 1 we … WebBoth the KPZ fixed point and TASEP are shown to be stochastic integrable systems in the sense that the time evolution of their transition probabilities can be linearized through a new Brownian scattering transform and its discrete analogue.

WebApr 6, 2024 · The Laplacian generates a Brownian motion, which we regard as a polymer in the space-time plane. The polymer is directed since it cannot bend backwards in time. The directed polymer is subject to an uncorrelated space-time random potential. The polymer energy is the sum of an elastic energy and a random potential energy.
