A Mathematical Note on the Value Positivity for Matrix Game

International Game Theory Review. 2020. Vol. 22. No. 1. P. 1-10.
Kreps V. L., Matveenko A.

We give a criterion of positivity for the value of a matrix game. We use the criterion to investigate conditions of positivity of value for two classes of games: payoff matrices with all elements outside of the main diagonal having the same sign and symmetric payoff matrices.
