Abstract

The field of game theory is a relatively new topic among mathematicians and economist. It was not until 1944 when John von Neumann and Oskar Morgenstern published the famous book "Theory of Games and Economic Behavior" was game theory a recognized field. The contributions of game theory were recognized in 1994 when John Nash, John C. Harsanyi and Reinhard Selten were awarded the Nobel prize in Economics for their work in game theory. Game theory encompasses a wide variety of games and situations that can be analyzed using the theoretical models developed through maximization methods in mathematics. The most basic of these models is the zero-sum two person game with finitely many strategies. These games can be solved using the minimax theorem. The minimax theorem was proven by John von Neumann in 1928 in his article "Zur Theorie der Gesellschaftsspiele" using topology and functional calculus. This theorem has proven to be extremely useful in analyzing and finding the Nash equilibrium outcome of two-person zero sum games and has acted as spring board in analyzing more complex games with contant-sum payoffs.
