Deterministic Analysis of Aleatoric Methods of Polynomial Factorization over Finite Fields

Univariate Polynomial Factorization Over Finite Fields

This paper shows that a recently proposed approach of D. Q. Wan to bivariate factorization over finite fields, the univariate factoring algorithm of V. Shoup, and the new bound of this paper for the average number of irreducible divisors of polynomials of a given degree over a finite field can be used to design a bivariate factoring algorithm that is polynomial for "almost all" bivariate polyno...

Deterministic distinct-degree factorization of polynomials over finite fields

A deterministic polynomial time algorithm is presented for finding the distinctdegree factorization of multivariate polynomials over finite fields. As a consequence, one can count the number of irreducible factors of polynomials over finite fields in deterministic polynomial time, thus resolving a theoretical open problem of Kaltofen from 1987.

Polynomial-Time Factorization of Multivariate Polynomials over Finite Fields

We present a probabilistic algorithm that finds the irreducible factors of a bivariate polynomial with coefficients from a finite field in time polynomial in the input size, i.e. in the degree of the polynomial and log (cardinality of field). The algorithm generalizes to multivariate polynomials and has polynomial running time for densely encoded inputs. Also a deterministic version of the algo...

𝒫-schemes and Deterministic Polynomial Factoring over Finite Fields

$\mathcal{P}$-schemes and Deterministic Polynomial Factoring over Finite Fields

We introduce a family of mathematical objects called $\mathcal{P}$-schemes, where $\mathcal{P}$ is a poset of subgroups of a finite group $G$. A $\mathcal{P}$-scheme is a collection of partitions of the right coset spaces $H\backslash G$, indexed by $H\in\mathcal{P}$, that satisfies a list of axioms. These objects generalize the classical notion of association schemes as well as the notion of $...
