确定性多项式因式分解方案

Schemes for Deterministic Polynomial Factoring

Gábor Ivanyos, Marek Karpinski, Nitin Saxena

摘要:

在这项工作中,我们涉及到确定性的复杂性的因子分解多项式(有限域)的某些组合对象,我们称之为M-计划。我们扩展了有限域上的条件确定性次指数时间多项式分解算法,得到了一个基本的m-方案。我们证明了m-方案的性质如何与有限域上因子分解多项式的确定性复杂性的改进相关,假设广义Riemann假设(GRH)。特别地,我们给出了第一个确定性的多项式时间算法(假设GRH),以找到一个非平凡的因子的多项式的素数的次数为n,其中(n-1)是一个光滑的数字。

英文摘要:

In this work we relate the deterministic complexity of factoring polynomials (over finite fields) to certain combinatorial objects we call m-schemes. We extend the known conditional deterministic subexponential time polynomial factoring algorithm for finite fields to get an underlying m-scheme. We demonstrate how the properties of m-schemes relate to improvements in the deterministic complexity of factoring polynomials over finite fields assuming the generalized Riemann Hypothesis (GRH). In particular, we give the first deterministic polynomial time algorithm (assuming GRH) to find a nontrivial factor of a polynomial of prime degree n where (n-1) is a smooth number.
