Abstract

We consider the Hamilton-Jacobi equation of eikonal type

H(u)=f(x),xΩ,H(\nabla u) = f(x), \quad x \in \Omega,

where HH is convex and ff is allowed to be discontinuous. Under a suitable assumption on ff we prove a comparison principle for viscosity sub- and supersolutions in the sense of Ishii. Furthermore, we develop an error analysis for a class of finite difference schemes, which are monotone, consistent and satisfy a suitable stability condition.
