A New Sparse Algorithm for Polynomial GCD over Integers

Qiao-Long Huang, Michael Monagan

We describe a new greatest common divisor (GCD) algorithm for polynomials with integer coefficients. The bit complexity of the new algorithm is polynomial in the input and output s…

Deterministic Polynomial-time Exact-root Computation for Sparse Polynomials with Bounded Total Degree

Qiao-Long Huang, Yichuan Cao, Ruichen Qiu +1

We study the problem of deterministically computing the exact root of a sparse polynomial in the multivariate setting. Let $f \in \F[x_1,\ldots,x_n]$ be a nonzero polynomial that i…

Output-sensitive Sparse Polynomial GCD over Finite Fields is NP-hard

Ruichen Qiu, Yichuan Cao, Qiao-Long Huang +2

In this paper, we prove that output-sensitive sparse polynomial GCD computation over finite fields is NP-hard under BPP many-one reduction. More precisely, for two sparse univariat…

Sparse Polynomial Divisibility Test over Finite Field is CoNP-hard

Yichuan Cao, Ruichen Qiu, Qiao-Long Huang +2

In this paper, we show that deciding whether a sparse polynomial does not divide another sparse polynomial exactly over finite fields is NP-hard under BPP many-one reductions. Equi…

Quasi-linear Time Multiplication of Sparse Polynomials with Integer Coefficients

Qiao-Long Huang, Yichuan Cao, Ruichen Qiu +1

Sparse polynomial multiplication is a fundamental problem in computer algebra and the theory of computation, and the development of a quasi-linear time output-sensitive multiplicat…
