Linear quadratic stochastic two-person zero-sum differential games in an infinite horizon
ESAIM: Control, Optimisation and Calculus of Variations, Tome 22 (2016) no. 3, pp. 743-769.

This paper is concerned with a linear quadratic stochastic two-person zero-sum differential game with constant coefficients in an infinite time horizon. Open-loop and closed-loop saddle points are introduced. The existence of closed-loop saddle points is characterized by the solvability of an algebraic Riccati equation with a certain stabilizing condition. A crucial result makes our approach work is the unique solvability of a class of linear backward stochastic differential equations in an infinite horizon.
