We study the long‐time behavior and regularity of the pathwise entropy solutions to stochastic scalar conservation laws with random‐in‐time spatially homogeneous fluxes and periodic initial data. We prove that the solutions converge to their spatial average, which is the unique invariant measure of the associated random dynamical system, and provide a rate of convergence, the latter being new even in the deterministic case for dimensions higher than 2. The main tool is a new regularization… 
Well-posedness of the non-local conservation law by stochastic perturbation
Stochastic non-local conservation law equation in the presence of discontinuous flux functions is considered in an $$L^{1}\cap L^{2}$$ L 1 ∩ L 2 setting. The flux function is assumed bounded and
Scalar conservation laws with rough flux and stochastic forcing
In this paper, we study scalar conservation laws where the flux is driven by a geometric Hölder p-rough path for some $$p\in (2,3)$$p∈(2,3) and the forcing is given by an Itô stochastic integral

We obtain several new regularity results for solutions of scalar conservation laws satisfying the genuine nonlinearity condition. We prove that the solutions are continuous outside of the jump set,

We develop a class of averaging lemmas for stochastic kinetic equations. The velocity is multiplied by a white noise which produces a remarkable change in time scale. Compared to the deterministic
