Fast Exact Algorithms Using Hadamard Product of Polynomials

Abstract: In this paper we develop an efficient procedure for computing a (scaled) Hadamard product for commutative polynomials. This serves as a tool to obtain faster algorithms for several problems. Our main algorithmic results include the following:

“…Brand et al have given the first FPT algorithm for multilinear monomial detection in the case of general circuit with run time randomized O * (4.32 k ) [8]. Recently, this problem has also been studied using the Hadamard product [3] of the given polynomial with the elementary symmetric polynomial (and differently using apolar bilinear forms [23]). Our proof of Theorem 1.5 shows that checking membership of f in the ideal x e 1 1 , .…”
