document: Doubly invariant equilibria of linear discrete-time games The notion of doubly invariant -LRB- DI -RRB- equilibrium is introduced . The concept extends controlled and robustly controlled invariance notions to the context of two-person dynamic games . Each player tries to keep the state in a region of state space independently of the actions of the rival player . The paper gives existence conditions , criteria and algorithms for the determination of DI equilibria of linear dynamic games in discrete time . Two examples illustrate the results . The first one is in the area of fault-tolerant controller synthesis . The second is an application to macroeconomics
