On semiring complexity of Schur polynomials

On semiring complexity of Schur polynomials Semiring complexity is the version of arithmetic circuit complexity that allows only two operations: addition and multiplication. We show that semiring complexity of a Schur polynomial $${s_\lambda(x_1,\dots,x_k)}$$ s λ ( x 1 , ⋯ , x k ) labeled by a partition $${\lambda=(\lambda_1\ge\lambda_2\ge\cdots)}$$ λ = ( λ 1 ≥ λ 2 ≥ ⋯ ) is bounded by $${O(\log(\lambda_1))}$$ O ( log ( λ 1 ) ) provided the number of variables k is fixed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Computational Complexity Springer Journals

Abstract

Semiring complexity is the version of arithmetic circuit complexity that allows only two operations: addition and multiplication. We show that semiring complexity of a Schur polynomial $${s_\lambda(x_1,\dots,x_k)}$$ s λ ( x 1 , ⋯ , x k ) labeled by a partition $${\lambda=(\lambda_1\ge\lambda_2\ge\cdots)}$$ λ = ( λ 1 ≥ λ 2 ≥ ⋯ ) is bounded by $${O(\log(\lambda_1))}$$ O ( log ( λ 1 ) ) provided the number of variables k is fixed.
