Stabilization of a Multi-Dimensional System of Hyperbolic Balance Laws

We are interested in the feedback stabilization of systems described by Hamilton-Jacobi type equations in ${\mathbb{R}}^n$. A reformulation leads to a a stabilization problem for a multi-dimensional system of $n$ hyperbolic partial differential equations. Using a novel Lyapunov function taking into account the multi-dimensional geometry we show stabilization in $L^2$ for the arising system using a suitable feedback control. We further present examples of such systems partially based on a forming process.
