%A Muhammad Wakhid Musthofa %J International Journal of Applied Mathematics and Statistics %T The Open-Loop Zero-Sum Linear Quadratic Impulse Free Descriptor Differential Game %X In this paper we study the open-loop zero-sum linear quadratic differential game for descriptor systems that have index one. 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.
