Abstract

We prove Tomaszewski's conjecture (1986): Let f:{-1,1}n ? R be of the form f(x)= ?i=1n ai xi. Then Pr[|f(x)| ? Var[f]] ? 1/2. Our main novel tools are local concentration inequalities and an improved Berry-Esseen inequality for first-degree functions on the discrete cube. These tools are of independent interest, and may be useful in the study of linear threshold functions and of low degree Boolean functions.
