Takashi Kamihigashi et al., « Necessary and Sufficient Conditions for a Solution of the Bellman Equation to be the Value Function: A General Principle », HAL-SHS : économie et finance, ID : 10670/1.dy30wp
In this paper, we give Necessary and Sufficient Conditions for a Solution of the Belman Equation to be the Value Function. This result is a general principle. It requires no structure beyond the common framework of discrete-time stationary optimization problems with time-additive returns. In particular, the state space X is an arbitrary set.
