In this paper we review known minimax results with applications ingame theory and show that these results are easy consequences of thefirst minimax result for a two person zero sum game with finite strategysets published by von Neumann in 1928: Among these results are thewell known minimax...

In this paper we review known minimax results with applications in game theory and showthat these results are easy consequences of the first minimax result for a two person zero sumgame with finite strategy sets published by von Neumann in 1928. Among these results are thewell known minimax...

In this paper we discuss the level set method of Joo and how to use it to give an elementary proof of the well-known Sion's minimax result. Although this proof technique is initiated by Joo and based on the inter-section of upper level sets and a clever use of the topological notion of...
