Query: A New Proof of Nonsignalling Multiprover Parallel Repetition Theorem   We present an information theoretic proof of the nonsignalling multiprover
parallel repetition theorem, a recent extension of its two-prover variant that
underlies many hardness of approximation results. The original proofs used de
Finetti type decomposition for strategies. We present a new proof that is based
on a technique we introduced recently for proving strong converse results in
multiuser information theory and entails a change of measure after replacing
hard information constraints with soft ones.
