Viscosity Solutions of Balanced Quasi-Monotone Fully Nonlinear Weakly Coupled Systems

Andreas Minne, Martin H. Strömqvist

We introduce so called balanced quasi-monotone systems. These are systems $F(x,r,p,X)=(F_1(x,r,p,X),\dots ,F_m(x,r,p,X))$, where $x$ belongs to a domain $\Omega$, $r=u(x)\in\mathbb{R}^m…
