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 Rⁿ. A reformulation leads to 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 L² for the arising system using a suitable feedback control. We further present examples of such systems partially based on a forming process.
