The Asymptotic Statistics of Random Covering Surfaces
Forum 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

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

The edge-regular complete maps
Open 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 ...

Open 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 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]
Memoirs 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 ...

Two gluing methods for string C-group representations of the symmetric groups [PDF]
The study of string C-group representations of rank at least \(n/2\) for the symmetric group \(S_n\) has gained a lot of attention in the last fifteen years. In a recent paper, Cameron et al.

Improved covering results for conjugacy classes of symmetric groups via hypercontractivity
Forum of Mathematics, SigmaWe 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 ...
