Differential Games and Hamilton-Jacobi-Isaacs Equations in Metric Spaces
Keywords:
Hamilton-Jacobi equations, metric space, differential games, viscosity solutions.Abstract
This paper is concerned with a game-based interpretation of Hamilton-Jacobi-Isaacs equations in metric spaces. We construct a two-person continuous-time game in a geodesic space and show that the value function, defined by an explicit representation formula, is the unique solution of the Hamilton-Jacobi equation. Our result develops, in a general geometric setting, the classical connection between differential games and the viscosity solutions to possibly nonconvex Hamilton Jacobi equations.
