... with Brouwer's fixed point theorem; that proof was later simplified by Kakutani. I have now found a much simpler proof based on the theorem of “supporting planes” of convex bodies—and I think that I see now a connection between these questions and the theory of convex bodies, which might be of some interest. 14...

... with convex images, it is possible to apply Kakutani fixed-point theorem to prove that the mapping has a fixed point, which is the desired equilib- rium. Hence Nash proves that every n-player finite game played with mixed strategies admits an equilibrium point. Moreover, for the first time in game theory he...

... to the (structural) parameters of his system, von Neumann offered an analytical treatment. Incidentally, when calculating the roots of the system, von Neumann used a Brouwer s fixed-point theorem. With it, he concluded, There are infinitely many solutions in existence. 51 These notes clearly instantiated...
