Time-inconsistent stochastic linear-quadratic control: characterization and uniqueness of equilibrium
Published 2017“…We derive a necessary and sufficient condition for equilibrium controls via a flow of forward–backward stochastic differential equations. When the state is one dimensional and the coefficients in the problem are all deterministic, we prove that the explicit equilibrium control constructed in [9] is indeed unique. …”

Time-Inconsistent Stochastic Linear--Quadratic Control
Published 2012“…We define an equilibrium, instead of optimal, solution within the class of open-loop controls, and derive a sufficient condition for equilibrium controls via a flow of forward--backward stochastic differential equations. When the state is one dimensional and the coefficients in the problem are all deterministic, we find an explicit equilibrium control. …”
