B. Lockwood, UNIQUENESS OF MARKOV-PERFECT EQUILIBRIUM IN INFINITE-TIME AFFINE-QUADRATIC DIFFERENTIAL-GAMES, Journal of economic dynamics & control, 20(5), 1996, pp. 751-765
This paper gives sufficient conditions for uniqueness of feedback Nash
(also known as Markov-perfect) equilibrium in scalar two-person infin
ite-time affine-quadratic differential games. Examples with multiple e
quilibria are also presented.
