2-closures of primitive permutation groups of holomorph type

open access: yesOpen Mathematics, 2019
The 2-closure G(2) of a permutation group G on a finite set Ω is the largest subgroup of Sym(Ω) which has the same orbits as G in the induced action on Ω × Ω.

Symmetric groups and conjugacy classes [PDF]

open access: yes, 2007
Let S_n be the symmetric group on n-letters. Fix n>5. Given any nontrivial $\alpha,\beta\in S_n$, we prove that the product $\alpha^{S_n}\beta^{S_n}$ of the conjugacy classes $\alpha^{S_n}$ and $\beta^{S_n}$ is never a conjugacy class.

On Schur 3-groups [PDF]

open access: yes, 2015
Let $G$ be a finite group. If $\Gamma$ is a permutation group with $G_{right}\leq\Gamma\leq Sym(G)$ and $\mathcal{S}$ is the set of orbits of the stabilizer of the identity $e=e_{G}$ in $\Gamma$, then the $\mathbb{Z}$-submodule $\mathcal{A}(\Gamma,G ...

Bi-quartic parametric polynomial minimal surfaces

open access: yes, 2015
Minimal surfaces with isothermal parameters admitting B\'{e}zier representation were studied by Cosin and Monterde. They showed that, up to an affine transformation, the Enneper surface is the only bi-cubic isothermal minimal surface.

Algebraically determined topologies on permutation groups [PDF]

open access: yes, 2012
In this paper we answer several questions of Dikran Dikranjan about algebraically determined topologies on the group of (finitely supported) permutations of a set X.Comment: 10 ...

1-Colored Archetypal Permutations and Strings of Degree n [PDF]

open access: yesMemoirs of the Scientific Sections of the Romanian Academy, 2012
New notions related to permutations are introduced here. We present the string of a 1-colored permutation as a closed planar curve, the fundamental 1-colored permutation as an equivalence class related to the equivalence in strings of the 1-colored ...

Impartial avoidance and achievement games for generating symmetric and alternating groups [PDF]

open access: yes, 2016
We study two impartial games introduced by Anderson and Harary. Both games are played by two players who alternately select previously-unselected elements of a finite group.

Improved covering results for conjugacy classes of symmetric groups via hypercontractivity

open access: yesForum of Mathematics, Sigma
We study covering numbers of subsets of the symmetric group $S_n$ that exhibit closure under conjugation, known as normal sets. We show that for any $\epsilon>0$ , there exists $n_0$ such that if $n>n_0$ and A is a normal ...
