Non-uniqueness of stationary measures for stochastic systems with almost surely invariant manifolds

Jacob Bedrossian, Alex Blumenthal, Sam Punshon-Smith

We develop a general framework for establishing non-uniqueness of stationary measures for stochastically forced dynamical systems possessing an almost surely invariant submanifold.…

Negative regularity mixing for random volume preserving diffeomorphisms

Jacob Bedrossian, Patrick Flynn, Sam Punshon-Smith

We consider the negative regularity mixing properties of random volume preserving diffeomorphisms on a compact manifold without boundary. We give general criteria so that the assoc…

Existence of stationary measures for partially damped SDEs with generic, Euler-type nonlinearities

Jacob Bedrossian, Alex Blumenthal, Keagan Callis +1

We study nonlinear energy transfer and the existence of stationary measures in a class of degenerately forced SDEs on with a quadratic, conservative nonlinearity $B(x…

A quantitative dichotomy for Lyapunov exponents of non-dissipative SDEs with an application to electrodynamics

Jacob Bedrossian, Chi-Hao Wu

In this paper we derive a quantitative dichotomy for the top Lyapunov exponent of a class of non-dissipative SDEs on a compact manifold in the small noise limit. Specifically, we p…

Kinetic shock profiles for the Landau equation

Dallas Albritton, Jacob Bedrossian, Matthew Novack

The physical quantities in a gas should vary continuously across a shock. However, the physics inherent in the compressible Euler equations is insufficient to describe the width or…
