Center node: "lower bound on weights of large degree threshold functions"
  Abstract: An integer polynomial $p$ of $n$ variables is called a \emph{threshold gate}#N#for a Boolean function $f$ of $n$ variables if for all $x \in \zoon$ $f(x)=1$#N#if and only if $p(x)\geq 0$. The \emph{weight} of a threshold gate is the sum#N#of its absolute values.#N#  In this paper we study how large a weight might be needed if we fix some#N#function and some threshold degree. We prove $2^{\Omega(2^{2n/5})}$ lower bound#N#on this value. The best previous bound was $2^{\Omega(2^{n/8})}$ (Podolskii,#N#2009).#N#  In addition we present substantially simpler proof of the weaker#N#$2^{\Omega(2^{n/4})}$ lower bound. This proof is conceptually similar to other#N#proofs of the bounds on weights of nonlinear threshold gates, but avoids a lot#N#of technical details arising in other proofs. We hope that this proof will help#N#to show the ideas behind the construction used to prove these lower bounds.
