....e#cient proofs of NP P poly. Similar results hold also for the system PCR (the natural common extension of Polynomial Calculus and Resolution) when the characteristic of the ground field is di#erent from 2. As a by product, we also improve on the small restriction switching lemma from [SBI02] by removing a square root from the final bound. This in particular implies that the (moderately) weak pigeonhole principle PHP n is hard for Res(# log n log log n) # Institute for Advanced Study, Princeton, US, on leave from Steklov Mathematical Institute, Moscow, Russia, ....
....n to n bits) is hard not only for Resolution but also for its extension PCR (Theorem 2. 19) These results were proved independently of [Kra02] the proof method uses the resolution width PC degree bounds from [ABRW00] cited above in combination with the machinery from the recent paper [SBI02] based upon the so called small restriction switching lemma. In order to bring these two together, we also introduce a special kind of random restrictions specifically tailored to deal with Nisan generators. Then, using a very simple reduction, we show that our generator is not only hard for ....
