Title:

Quantitative homogenization of convex Hamilton-Jacobi equations with Neumann type boundary conditions

Abstract：

We study the periodic homogenization for convex Hamilton-Jacobi equations on perforated domains under the Neumann type boundary conditions. We consider two types of conditions, the oblique derivative boundary condition and the prescribed contact angle boundary condition, which is important in the front propagation. We first establish the representation formula by using the Skorokhod problem and modified Lagrangians. We then obtain the optimal rate of convergence O(ε) for homogenization by developing techniques in \cite{TY, HJMT} to apply to the Neumann type problems.
