摘要:
[5]中已证明对数Sobolev不等式与哈密顿-雅可比方程解的超收缩性等价。本文考虑哈密顿-雅可比方程的半拉格朗日近似方案,并证明离散问题的解满足超收缩估计。我们将这一性质应用于获得截断误差集的误差估计。
英文摘要:
The equivalence between logarithmic Sobolev inequalities and hypercontractivity of solutions of Hamilton-Jacobi equations has been proved in [5]. We consider a semi-Lagrangian approximation scheme for the Hamilton-Jacobi equation and we prove that the solution of the discrete problem satisfies a hypercontractivity estimate. We apply this property to obtain an error estimate of the set where the truncation error is concentrated.
