On Positive Game Matrices and Their Extensions
Indian Statistical Institute 203 Barrackpore Trunk Road, Calcutta 35, India
In this paper we study some relations between the optimal strategies, the characteristic roots and the characteristic vectors of a positive square matrix whose rows and columns correspond to the pure strategy spaces of players in a zero-sum two-person game. Further we study a property of the game values of positive matrices that commute. The results are extended to infinite games on the unit square, with positive kernels as pay-off functions.
