Permutations over cyclic groups [PDF]

open access: bronzeEuropean Journal of Combinatorics, 2012
Generalizing a result in the theory of finite fields we prove that, apart from a couple of exceptions that can be classified, for any elements $a_1,...,a_m$ of the cyclic group of order $m$, there is a permutation $\pi$ such that $1a_{\pi(1)}+...+ma_{\pi(

A Cyclic Permutation Approach to Removing Spatial Dependency between Clustered Gene Ontology Terms [PDF]

open access: goldBiology
Traditional gene set enrichment analysis falters when applied to large genomic domains, where neighboring genes often share functions. This spatial dependency creates misleading enrichments, mistaking mere physical proximity for genuine biological ...

Permutation Polytopes of Cyclic Groups [PDF]

open access: diamondDiscrete Mathematics & Theoretical Computer Science, 2012
We investigate the combinatorics and geometry of permutation polytopes associated to cyclic permutation groups, i.e., the convex hulls of cyclic groups of permutation matrices.

Infinity-Norm Permutation Covering Codes from Cyclic Groups [PDF]

open access: greenIEEE Transactions on Information Theory, 2017
We study covering codes of permutations with the $\ell_\infty$-metric. We provide a general code construction, which uses smaller building-block codes.

Cyclic permutations: Degrees and combinatorial types [PDF]

open access: greenJournal of Combinatorial Theory, Series A, 2021
This note will give an enumeration of $n$-cycles in the symmetric group ${\mathcal S}_n$ by their degree (also known as their cyclic descent number) and studies similar counting problems for the conjugacy classes of $n$-cycles under the action of the rotation subgroup of ${\mathcal S}_n$.

On a problem of cyclic permutations of integers

open access: bronzeDiscrete Applied Mathematics, 1980
AbstractWe consider a problem of cyclic permutations of integers arising in the field of memory technologies for computer systems, and we solve it in the more general case of reals.

On Cyclic Schur-Positive Sets of Permutations [PDF]

open access: diamondThe Electronic Journal of Combinatorics, 2020
We introduce a notion of cyclic Schur-positivity for sets of permutations, which naturally extends the classical notion of Schur-positivity, and it involves the existence of a bijection from permutations to standard Young tableaux that preserves the cyclic descent set.

Dynamic Injection and Permutation Coding for Enhanced Data Transmission [PDF]

open access: yesEntropy
In this paper, we propose a novel approach to enhance spectral efficiency in communication systems by dynamically adjusting the mapping between cyclic permutation coding (CPC) and its injected form.

Descents of $\lambda$-unimodal cyclic permutations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
We prove an identity conjectured by Adin and Roichman involving the descent set of $\lambda$-unimodal cyclic permutations. These permutations appear in the character formulas for certain representations of the symmetric group and these formulas are ...
