Sparsification lemma

In this talk, I will present a lemma which shows that, for any fixed \epsilon > 0, an arbitrary k-CNF formula can be represented as a disjunction of 2^{\epsilon n} k-CNF formulas that are sparse, that is, each has O(n) clauses. I will discuss the motivation for the lemma and mention its key applications.

Joint work with R. Impagliazzo and F. Zane .
