Weak Approachability

Author

Listed:
  • Nicolas Vieille

Abstract

In this paper, we study repeated games with vector payoffs. Following Blackwell [2], we define weak approachability and its dual property, weak excludability. We use results from differential games with fixed duration to prove that every set is either weakly approachable or weakly excludable.
