Practical polynomial factoring in polynomial time [PDF]

open access: yesProceedings of the 36th international symposium on Symbolic and algebraic computation, 2011
State of the art factoring in Q[x] is dominated in theory by a combinatorial reconstruction problem while, excluding some rare polynomials, performance tends to be dominated by Hensel lifting. We present an algorithm which gives a practical improvement (less Hensel lifting) for these more common polynomials.

A heuristic technique for decomposing multisets of non-negative integers according to the Minkowski sum [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2022
We study the following problem. Given a multiset $M$ of non-negative integers, decide whether there exist and, in the positive case, compute two non-trivial multisets whose Minkowski sum is equal to $M$.

Some Families of Differential Equations Associated with Multivariate Hermite Polynomials

open access: yesFractal and Fractional, 2023
In this article, the recurrence relations and shift operators for multivariate Hermite polynomials are derived using the factorization approach. Families of differential equations, including differential, integro–differential, and partial differential ...

Relevance of Factorization Method to Differential and Integral Equations Associated with Hybrid Class of Polynomials

open access: yesFractal and Fractional, 2021
This article has a motive to derive a new class of differential equations and associated integral equations for some hybrid families of Laguerre–Gould–Hopper-based Sheffer polynomials.

Factorization of motion polynomials [PDF]

open access: yesJournal of Symbolic Computation, 2019
In this paper, we consider the existence of a factorization of a monic, bounded motion polynomial. We prove existence of factorizations, possibly after multiplication with a real polynomial and provide algorithms for computing polynomial factor and factorizations.

The Numerical Factorization of Polynomials [PDF]

open access: yesFoundations of Computational Mathematics, 2015
Polynomial factorization in conventional sense is an ill-posed problem due to its discontinuity with respect to coefficient perturbations, making it a challenge for numerical computation using empirical data. As a regularization, this paper formulates the notion of numerical factorization based on the geometry of polynomial spaces and the ...

Bilinear character correlators in superintegrable theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We continue investigating the superintegrability property of matrix models, i.e. factorization of the matrix model averages of characters. This paper focuses on the Gaussian Hermitian example, where the role of characters is played by the Schur functions.

Factoring octonion polynomials [PDF]

open access: yesInternational Journal of Algebra and Computation, 2020
We provide an analogue of Wedderburn’s factorization method for central polynomials with coefficients in an octonion division algebra, and present an algorithm for fully factoring polynomials of degree [Formula: see text] with [Formula: see text] conjugacy classes of roots, counting multiplicities.
