Περίληψη:
Can Game Theory predict rational behavior? In two- player zero-sum games the Nash equilibrium makes rather convincing predictions, which can also be computed efficiently with linear programming. We show, however, that the Nash equilibrium is in general intractable, casting doubt on whether it always truly captures the behavior of computationally bounded agents. We also discuss ways to overcome this intractability barrier, including approximation, dynamics, and studying well- behaved families of games. We conclude with a broader discussion of the interactions of Game Theory and the Theory of Computation.

Περίληψη:
Universal Taylor Series, as defined by Vassili Nestoridis, have counter-intuitive approximation properties outside the domain of definition of the associated holomorphic functions. This talk will indicate how potential theory sheds new light on this phenomenon. In particular, it will describe recent answers to open questions concerning the boundary behaviour of such functions and their relationship with conformal mappings.
