The paper is concerned with the randomized Nash equilibrium for a nonzero-sum deterministic differential game of two players. We assume that each player is informed about the control of the partner realized up to the current moment. Therefore, the game is formalized in the class of randomized non-anticipative strategies. The main result of the paper is the characterization of a set of Nash values considered as pairs of expected players' outcomes. The characterization involves the value functions of the auxiliary zero-sum games. As a corollary we get that the set of Nash values in the case when the players use randomized strategies is a convex hull of the set of Nash values in the class of deterministic strategies. Additionally, we present an example showing that the randomized strategies can enhance the outcome of the players.
Keywords: differential games, Nash equilibrium, randomized strategies.
