A Tight Characterization of NP with 3 Query PCPs
It is known that there exists a PCP characterization of NP where the verifier makes 3 queries and has a onesided error that is bounded away from 1; and also that 2 queries do not ...

Gowers uniformity, influence of variables, and PCPs
Gowers [Gow98, Gow01] introduced, for d 1, the notion of dimension-d uniformity Ud (f) of a function f : G C, where G is a finite abelian group. Roughly speaking, if a function ...

The PCP theorem by gap amplification
The PCP theorem [3, 2] says that every language in NP has a witness format that can be checked probabilistically by reading only a constant number of bits from the proof. The cele...
