Letf: {0, 1}n→ {0, 1} be a boolean function, and letf∧(x,y) =f(x∧y) denote theAND-functionoff, wherex∧ydenotes bit-wise AND. We study the deterministic communication complexity off∧and show that, up to a lognfactor, it is bounded by a polynomial in the logarithm of the real rank of the communication matrix off∧. This comes within a lognfactor of establishing the log-rank conjecture for AND-functions withno assumptionsonf. Our result stands in contrast with previous results on special cases of the log-rank conjecture, which needed significant restrictions onfsuch as monotonicity or low F2-degree. Our techniques can also be used to prove (within a lognfactor) alifting theoremfor AND-functions, stating that the deterministic communication complexity off∧is polynomially related to theAND-decision tree complexityoff.The results rely on a new structural result regarding boolean functionsf: {0, 1}n→ {0, 1} with a sparse polynomial representation, which may be of independent interest. We show that if the polynomial computingfhas few monomials then the set system of the monomials has a small hitting set, of size poly-logarithmic in its sparsity. We also establish extensions of this result to multi-linear polynomialsf: {0, 1}n→ with a larger range.
