Factoring polynomials with rational coefficients [PDF]
Mathematische Annalen, 1982 This paper describes a polynomial-time algorithm for the factorization of primitive polynomials \(f\in \mathbb Z[X]\) into irreducible factors. The number of bit operations used by the algorithm is \(O(n^{12} + n^9(\log \vert f\vert)^3)\), where \(n\) is the degree of \(f\) and \(\vert \sum_i a_iX^i \vert = (\sum_i a_i^2)^{1/2})\).

A diagrammatic approach to Kronecker squares [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 In this paper we improve a method of Robinson and Taulbee for computing Kronecker coefficients and show that for any partition $\overline{ν}$ of $d$ there is a polynomial $k_{\overline{ν}}$ with rational coefficients in variables $x_C$, where $C$ runs ...

Algebraic Numbers Satisfying Polynomials with Positive Rational Coefficients [PDF]
Journal of Numbers, 2014 A theorem of Dubickas, affirming a conjecture of Kuba, states that a nonzero algebraic number is a root of a polynomial f with positive rational coefficients if and only if none of its conjugates is a positive real number. A certain quantitative version of this result, yielding a growth factor for the coefficients of f similar to the condition of the ...
