Stochastic homogenization of a class of quasiconvex and possibly degenerate viscous HJ equations in 1d (2402.17031v1)
Published 26 Feb 2024 in math.AP
Abstract: We prove homogenization for possibly degenerate viscous Hamilton-Jacobi equations with a Hamiltonian of the form $G(p)+V(x,\omega)$, where $G$ is a quasiconvex, locally Lipschitz function with superlinear growth, the potential $V(x,\omega)$ is bounded and Lipschitz continuous, and the diffusion coefficient $a(x,\omega)$ is allowed to vanish on some regions or even on the whole $\mathbb{R}$. The class of random media we consider is defined by an explicit scaled hill condition on the pair $(a,V)$ which is fulfilled as long as the environment is not ``rigid''.
