RT Monograph SR 00 A1 Cardaliaguet, P. T1 A Differential Game With One Target and Two Players YR 1994 FD 1994-08 SP 7 AB We study a two players-differential game in which one player wants the state of the system to reach an open target and the other player wants the state of the system to avoid the target. We characterize the victory domains of each player as the largest set satisfying some geometric conditions and we show a "barrier phenomenon" on the boundary of the victory domains.
