Title
Sums of read-once formulas: How many summands are necessary?
Abstract
•Every multilinear n-variate polynomial can be expressed as the sum of ⌈3×2n−4⌉ Read-Once Polynomials ROPs.•There exist (non-explicit) multilinear n-variate polynomials needing Ω(2nn2) summands when expressed as sums of ROPs.•The polynomials Snn−1 cannot be written as the sum of any k ROPs if k<⌈n/2⌉.•Certain explicit 4-variate multilinear polynomials cannot be expressed as the sum of two ROPs.
