Efficient Algorithms for Permutation Arrays from Permutation Polynomials [PDF]
We develop algorithms for computing permutation polynomials (PPs) using normalization, so-called F-maps and G-maps, and the Hermite criterion. This allows for a more efficient computation of PPs for larger degrees and for larger finite fields.

Permutations of massive vacua [PDF]
We discuss the permutation group G of massive vacua of four-dimensional gauge theories with N $$ \mathcal{N} $$ = 1 supersymmetry that arises upon tracing loops in the space of couplings. We concentrate on superconformal N $$ \mathcal{N} $$ = 4 and N $$ \

On permutation polynomials over finite fields [PDF]
A polynomial f over a finite field F is called a permutation polynomial if the mapping F→F defined by f is one-to-one. In this paper we consider the problem of characterizing permutation polynomials; that is, we seek conditions on the coefficients of a ...

Tree snumeration polynomials on separable permutations
Summary: \textit{I. M. Pak} and \textit{A. E. Postnikov} [Russ. Math. Surv. 45, No. 3, 220--221 (1990; Zbl 0744.05020); translation from Usp. Mat. Nauk 45, No. 3(273), 193--194 (1990)] introduced a tree enumeration polynomial \(f_G\) on graphs, as a multivariate generalization of Cayley's formula, and demonstrated an amazing reciprocity property.

Symplectic Spreads and Permutation Polynomials [PDF]
Every symplectic spread of PG(3,q), or equivalently every ovoid of Q(4,q), is shown to give rise to a certain family of permutation polynomials of GF(q) and conversely. This leads to an algebraic proof of the existence of the Tits-Luneburg spread of W(2^{2h+1}) and the Ree-Tits spread of W(3^{2h+1}), as well as to a new family of low-degree permutation

Inverses for Fourth-Degree Permutation Polynomials Modulo 32Ψ or 96Ψ, with Ψ as a Product of Different Prime Numbers Greater than Three [PDF]
In this paper, we address the inverse of a true fourth-degree permutation polynomial (4-PP), modulo a positive integer of the form 32kLΨ, where kL∈{1,3} and Ψ is a product of different prime numbers greater than three. Some constraints are considered for

Permutation polynomials and group permutation polynomials [PDF]
Permutation polynomials of the form xτf (x3) over a finite field give rise to group permutation polynomials. We give a group theoretic criterion and some other criteria in terms of symmetric functions and power functions.

A Class of New Permutation Polynomials over F2n
In this paper, according to the known results of some normalized permutation polynomials with degree 5 over F2n, we determine sufficient and necessary conditions on the coefficients b1,b2∈F2n2 such that fx=x3x¯2+b1x2x¯+b2x permutes F2n.
