The Asymptotic Statistics of Random Covering Surfaces

open access: yesForum of Mathematics, Pi, 2023
Let $\Gamma _{g}$ be the fundamental group of a closed connected orientable surface of genus $g\geq 2$ . We develop a new method for integrating over the representation space $\mathbb {X}_{g,n}=\mathrm {Hom}(\Gamma _{g},S_{n})$ , where

The edge-regular complete maps

open access: yesOpen Mathematics, 2020
A map is called edge-regular if it is edge-transitive but not arc-transitive. In this paper, we show that a complete graph Kn{K}_{n} has an orientable edge-regular embedding if and only if n=pd>3n={p}^{d}\gt 3 with p an odd prime such that pd≡3{p}^{d ...

Shear Bearing Capacity of Framework Joints of Steel‐Reinforced Concrete‐Filled Circular Steel Tube

open access: yesAdvances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020
In this paper, in order to investigate the shear mechanism and shear capacity of framework joints of steel‐reinforced concrete‐filled circular steel tube (SRCFCST), a numerical finite element model reflecting the mechanical behavior of framework joints of SRCFCST column‐reinforced concrete beam is established through simulating concrete by the damage ...

On finite dual Cayley graphs

open access: yesOpen Mathematics, 2020
A Cayley graph Γ\Gamma on a group G is called a dual Cayley graph on G if the left regular representation of G is a subgroup of the automorphism group of Γ\Gamma (note that the right regular representation of G is always an automorphism group of Γ ...

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.

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 ...

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 ...
