(external pageASIC) that took place in Molveno, Italy, on the 24-29 June.
Title
Regarding deterministic extensions of quantum theory and proving that Einstein was right
Abstract
In previous editions of ASIC, I presented solution concepts and algorithms on non-Nashian game theory and showed how I successfully extended Hofstadter's superrationality to non-symmetric games and to games in extensive form (with perfect or imperfect information). Non-Nashian game theory differs from Nash-equilibrium-based game theory in that deviations are not unilateral, and more specifically the superrational approach, which I focus on, is based on perfect prediction (i.e. the prediction depends counterfactually on the decision), leading to an at-most-unique solution. In this talk, I will present recently published research ("Nashian game theory is incompatible with quantum physics", in Springer's Quantum Studies: Mathematics and Foundations) showing the close relevance of the non-Nashian approach to quantum physics, and give a status report on my efforts to prove that Einstein was right all along about the existence of deterministic extension theories of quantum physics. In particular I will show how quantum experiments can easily be represented as big games between observers and the universe, in extensive form and with imperfect information, and how impossibility theorems, far from proving Einstein wrong, only in fact prove that the suggested approach must involve a non-Nashian solution concept.
