Abstract

A depth 3 arithmetic circuit can be viewed as a sum of products of linear functions. We prove an exponential complexity lower bound on depth 3 arithmetic circuits computing some natural symmetric functions over a finite field $F$. Also, we study the complexity of the functions $f : D^n \to F$ for subsets $D \subset F$. In particular, we prove an exponential lower bound on the complexity of a depth 3 arithmetic circuit which computes the determinant or the permanent of a matrix considered as functions $f : (F^*)^{n^2} \to F$
