The Nonconvex Multi-Dimensional Riemann Problem for Hamilton-Jacobi Equations
Abstract
Simple inequalities are presented for the Riemann problem for a Hamilton Jacobi equation in N space dimension when neither the initial data nor the Hamiltonian need be convex (or concave). The initial data is globally continuous, affine in each orthant, with a possible jump in normal derivative across each coordinate plane, x sub i = 0. The inequalities become equalities whereever a maxmin equals a minmax and thus an exact closed form solution to this problem is then obtained. Keywords: Hamilton Jacobi equations; Riemann problem; Godunov scheme.
