Order recognition by Schubert polynomials generated by optical near-field statistics via nanometre-scale photochromism

open access: yesScientific Reports, 2022
Irregular spatial distribution of photon transmission through a photochromic crystal photoisomerized by a local optical near-field excitation was previously reported, which manifested complex branching processes via the interplay of material deformation ...

Fixed Point Polynomials of Permutation Groups [PDF]

open access: yes, 2013
In this paper we study, given a group $G$ of permutations of a finite set, the so-called fixed point polynomial $\sum_{i=0}^{n}f_{i}x^{i}$, where $f_{i}$ is the number of permutations in $G$ which have exactly $i$ fixed points.

A Coefficient Test for Quintic Permutation Polynomials Over Integer Rings

open access: yesIEEE Access, 2018
For selecting appropriate permutation polynomials (PPs) in practical applications, it is necessary to know the coefficients of the polynomial since a brute-force exhaustive search is impractical when the number of PPs is large.

Characters of symmetric groups in terms of free cumulants and Frobenius coordinates [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
Free cumulants are nice and useful functionals of the shape of a Young diagram, in particular they give the asymptotics of normalized characters of symmetric groups $\mathfrak{S}(n)$ in the limit $n \to \infty$.

On generalized Rédei functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
A generalization of Rédei functions to polynomial vectors in n indeterminates over finite fields or residue class rings of integers is given by considering special types of polynomial vectors.

A note on some identities of derangement polynomials

open access: yesJournal of Inequalities and Applications, 2018
The problem of counting derangements was initiated by Pierre Rémond de Montmort in 1708 (see Carlitz in Fibonacci Q. 16(3):255–258, 1978, Clarke and Sved in Math. Mag. 66(5):299–303, 1993, Kim, Kim and Kwon in Adv. Stud. Contemp. Math. (Kyungshang) 28(1):

Analysis of cubic permutation polynomials for turbo codes

open access: yes, 2012
Quadratic permutation polynomials (QPPs) have been widely studied and used as interleavers in turbo codes. However, less attention has been given to cubic permutation polynomials (CPPs).

Stack-Sortable Permutations and Polynomials

open access: yesTurkish Journal of Mathematics, 2009
The Catalan numbers show up in a diverse variety of counting problems. In this note we give yet another characterization of the Catalan number C(n). It is characterized as the dimension of a certain space of multilinear polynomials by exhibiting a basis.
