“…Early papers in mathematical finance to study the game-theoretic approach to time-inconsistent problems are [2,15,16,17] where PDE methods for specific time-inconsistent problems -that are similar to the general method relying on the extended HJB system of [6,7] -are developed. Recent publications that use different versions of the extended HJB system to study time-inconsistent stochastic control problems include [4,8,9,19,23,25,26,27,35]. In [14], the equilibrium of a time-inconsistent control problem is characterized by a stochastic maximum principle.…”
