We present both necessary and sufficient conditions for the existence of an open-loop Nash equilibrium. We also relate the existence of an open-loop Nash equilibrium with the theory of invariant subspaces. Keywords: zero-sum linear quadratic differential game, open-loop information structure, descriptor systems.
