Theorem
Let $G$ be a two-person zero-sum game.
Let $G$ have more than one equilibrium point.
Then every equilibrium point of $G$ has the same payoff.
Proof
This theorem requires a proof. In particular: Stated without proof, or even an explanatory comment on its scope of applicability, in Davis. This work is too vague to be useful. I am going to have to use a different work. You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof. To discuss this page in more detail, feel free to use the talk page. When this work has been completed, you may remove this instance of {{ProofWanted}} from the code.If you would welcome a second opinion as to whether your work is correct, add a call to {{Proofread}} the page. |
