Abstract

The aim of this note is to give a Beckmann-type problem as well as the corresponding optimal mass transportation problem associated with a degenerate Hamilton-Jacobi equation H ( x , ∇ u ) = 0 , H(x,\nabla u)=0, coupled with non-zero Dirichlet condition u = g u=g on ∂ Ω \partial \Omega . In this article, the Hamiltonian H H is continuous in both arguments, coercive and convex in the second, but not enjoying any property of existence of a smooth strict sub-solution. We also provide numerical examples to validate the correctness of theoretical formulations.

退化Hamilton-Jacobi方程的Beckmann型问题

本文的目的是给出一个beckmann型问题以及与简并Hamilton-Jacobi方程H(x，∇u)=0, H(x, \nabla u)=0，以及∂Ω \partial\Omega上的非零Dirichlet条件u=g u=g相关的相应的最优质量输运问题。在本文中，哈密顿矩阵H H在两个论证中都是连续的，在第二个论证中是强制的和凸的，但不具有光滑严格子解存在的性质。通过数值算例验证了理论公式的正确性。
