Why was John Nash's 1950 Game Theory paper such a big deal?
Joël, Of course there are also issues with the notion of value for zero-sum 2-person games, like the need to have mixed strategies which is problematic in various cases (and various others issues). Once you apply Von Neumann and Morgenstern utility theory on mixed outcomes you often loose the zero-sum property. But I agree that the notion of a value of zero-sum games is also very important. |

Dear Joël, I agree. To a large extent Nash equilibrium is a miracle concept leading to (almost) all the problems in applied game theory. It often represents genuine problems and shortcomings not only of economics theory but also of economics reality. Certainly this is something we, as mathematicians can celebrate and be enthusiastic about! |

First PhD in pure math and the second PhD in applied math
I am aware of several such cases. (Prhaps in Israel and Europe there is more flexibility.) |

Infinitely many primes, and Mobius randomness in sparse sets
Dear Joro, Yes, I think we need to regard it as artificial. Probably Problems 2 and 3 are more "imune" against such examples. |
