From optimal control to non-cooperative differential games: a homotopy approach. (English) Zbl 1235.91023
Summary: We propose a new approach to the study of Nash equilibrium solutions to non-cooperative differential games. The original problem is embedded in a one-parameter family of differential games, where the parameter \(\theta \in [0,1]\) accounts for the strength of the second player. When \(\theta = 0\), the second player adopts a myopic strategy and the game reduces to an optimal control problem for the first player. As \(\theta \) becomes strictly positive, Nash equilibrium solutions can be obtained by studying a bifurcation problem for the corresponding system of Hamilton-Jacobi equations.
