我们研究梯度正齐次的二阶、简并和拟线性 Hamilton-Jacobi 方程的随机齐次化。其中包括受迫平均曲率运动方程和其他描述水平集几何运动的方程,以及一大类粘性非凸哈密顿-雅可比方程。主要结果包括此类方程的定性随机均质化的第一个证明。我们还提出了定量误差估计,给出了均质化的代数率。
We study random homogenization of second-order, degenerate and quasilinear Hamilton-Jacobi equations which are positively homogeneous in the gradient. Included are the equations of forced mean curvature motion and others describing geometric motions of level sets as well as a large class of viscous, non-convex Hamilton-Jacobi equations. The main results include the first proof of qualitative stochastic homogenization for such equations. We also present quantitative error estimates which give an algebraic rate of homogenization.
