Hi everyone,
Please come now to Yuri Gurevich's talk in Star! The talk on no-go
theorems is a "go," :-) and it looks likely to be extremely interesting.
Best,
Scott

Yuri Gurevich: Hidden Variables: Value and Expectation No-Go

Abstract: No-go theorems assert that hidden-variable theories, subject to
appropriate hypotheses, cannot reproduce the predictions of quantum theory.
We examine two species of such theorems, value no-go theorems and
expectation no-go theorems. The former assert that hidden-variables cannot
match the predictions of quantum theory about the possible values resulting
from measurements; the latter assert that hidden-variables cannot match the
predictions of quantum theory about the expectation values of measurements.
We sharpen the known results of both species, which allows us to clarify
the similarities and differences between the two species. We also repair
some flaws in existing definitions and proofs. This is joint work with
Andreas Blass of the University of Michigan. The paper can be found at
arXiv:1509.06896.
