The principal tool used in the proof is a Lefschetz fixed point theorem for multivalued maps which extends the well known "Eilenberg-Montgomery fixed point theorem" to nonacyclic spaces. Special cases of the existence theorem are also discussed.en-USPure Strategy Nash Equilibrium Points and the Lefschetz Fixed Point TheoremWorking Paper
