Monotone separations for constant degree polynomials
Pavel Hrubeš,Amir Yehudayoff +1 more
TL;DR: A separation between monotone and general arithmetic formulas for polynomials of constant degree is proved and the upper bound is achieved by a homogeneous arithmetic formula.

Homogeneous formulas and symmetric polynomials
Pavel Hrubeš,Amir Yehudayoff +1 more
TL;DR: The arithmetic formula complexity of the elementary symmetric polynomials is investigated and it is shown that every multilinear homogeneous formula computing S^k_n has size at least $${k^{\Omega(\log k)}n}$$ and that S can be computed by homogeneous formulas of size k.
Journal Article
On ε-sensitive monotone computations.
TL;DR: It is shown that strong-enough lower bounds on monotone arithmetic circuits or the non-negative rank of a matrix imply unconditional lower bounds in arithmetic or Boolean circuit complexity.
Journal Article
Non-commutative circuits and the sum-of-squares problem.
TL;DR: In this paper, a connection between lower bounds on the size of non-commutative arithmetic circuits and a problem about commutative degree four polynomials, the classical sum-of-squares problem, was made.
Journal ArticleDOI
On $$\epsilon$$ ϵ -sensitive monotone computations
TL;DR: It is shown that strong-enough lower bounds on monotone arithmetic circuits or the nonnegative rank of a matrix imply unconditional lower bounds in arithmetic or Boolean circuit complexity.
