Consider an $N$-step delayed information-sharing pattern with $N\geq 2$, in which each controller has access to the common information subject to an $N$-step delay. Policies are ca…

Witsenhausen's counterexample is a decentralized stochastic control problem in which the controller mappings are based on different observations and the objective is to minimize th…

A decentralized linear system has state dynamics and local observations of the form … with … A decentralized system is stabilizable when its controllers can stabilize the plant, an…

Bounded-SNR conjecture. The SNR is bounded, and implicit communication may not be crucial for constant-ratio optimality.
