In-situ inversion of a cyclic permutation [PDF]

open access: yesInformation Processing Letters, 1987
An algorithm is developed for the in-situ inversion of a cyclic permutation represented in an array. The emphasis is on the quo modo rather than the quod**; we are interested in finding concepts and notations for dealing more effectively with formal developments and proofs of such algorithms, rather than in this particular algorithm itself.

The Topological Entropy of Cyclic Permutation Maps and Some Chaotic Properties on Their MPE sets

open access: yesComplexity, 2020
In this paper, we study some chaotic properties of s-dimensional dynamical system of the form Ψa1,a2,…,as=gsas,g1a1,…,gs−1as−1, where ak∈Hk for any k∈1,2,…,s, s≥2 is an integer, and Hk is a compact subinterval of the real line ℝ=−∞,+∞ for any k∈1,2,…,s ...

Application of a permutation group on sasirangan pattern

open access: yesDesimal, 2021
A permutation group is a group of all permutations of some set. If the set that forms a permutation group is the n-first of natural number, then a permutation group is called a symmetry group.

On the crossing numbers of join products of W_{4}+P_{n} and W_{4}+C_{n} [PDF]

open access: yesOpuscula Mathematica, 2021
The crossing number \(\mathrm{cr}(G)\) of a graph \(G\) is the minimum number of edge crossings over all drawings of \(G\) in the plane. The main aim of the paper is to give the crossing number of the join product \(W_4+P_n\) and \(W_4+C_n\) for the ...

On the crossing numbers of join products of five graphs of order six with the discrete graph [PDF]

open access: yesOpuscula Mathematica, 2020
The main purpose of this article is broaden known results concerning crossing numbers for join of graphs of order six. We give the crossing number of the join product \(G^{\ast} + D_n\), where the disconnected graph \(G^{\ast}\) of order six consists of ...

On Cyclic Schur-Positive Sets of Permutations [PDF]

open access: yesThe 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.

Cyclic permutations: Degrees and combinatorial types [PDF]

open access: yesJournal 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 ${\mathcal S}_n$.

Rational and quasi-permutation representations of holomorphs of cyclic $p$-groups [PDF]

open access: yesInternational Journal of Group Theory, 2022
‎For a finite group $G$‎, ‎three of the positive integers governing its‎ ‎representation theory over $\mathbb{C}$ and over $\mathbb{Q}$ are‎ ‎$p(G),q(G),c(G)$‎.

Periodic Patterns of Signed Shifts [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
The periodic patterns of a map are the permutations realized by the relative order of the points in its periodic orbits. We give a combinatorial description of the periodic patterns of an arbitrary signed shift, in terms of the structure of the descent ...
