Viscosity solutions for weakly coupled systems of first-order partial differential equations
This paper is concerned with some weakly coupled systems of first order partial differential equations. The coupling concerns the zero order terms and is such that, at least finally, the maximum principle holds. This context allows for an adaptation of the notion of viscosity solutions and leads to existence and uniqueness results with applications to Random evolutions.
