Deterministic indeterminacy of CHSH-solving protocols

Dmitri Gavinsky
IM
Friday, 15. February 2019 - 13:30 to 15:00

in IM, rear building, ground floor

How unpredicatble is the behaviour of efficient entagled players in the CHSH game?
We will discuss this question from both qualitative and quantitative point viewpoints.

How to compute random Boolean function over the reals.

in IM, rear building, ground floor

We consider the problem of defining a Boolean function by means of a first-order formula over the reals. We discuss the connection of this problem with other questions in computational complexity. We also outline some bounds on the size of formulas computing a random Boolean function.

I will continue with the construction of an extractor for zero fixing sources of triple logarithmic size.
