WebUsing the concepts of convex duality and density, in this paper we show that the existence of a barrier certificate is also necessary for safety. WebThis paper presents a methodology for safety verification of continuous and hybrid systems in the worst-case and stochastic settings. In the worst-case setting, a function of state termed barrier certificate is used to certify that all trajectories of the system starting from a given initial set do not enter an unsafe region. No explicit computation of reachable sets …
