Generating infinite symmetric groups [PDF]
Let S=Sym(\Omega) be the group of all permutations of an infinite set \Omega. Extending an argument of Macpherson and Neumann, it is shown that if U is a generating set for S as a group, respectively as a monoid, then there exists a positive integer n ...

The Characterizations of δ — Algebras with Their Ideals
We explored new algebra structures such as δ —algebra, δ —subalgebra and δ —ideal in this work. In addition, we study their fundamental characteristics and their connections with other algebras, such as d/ρ/BCK - algebras, d/ρ/BCK – subalgebras and d/ρ ...

The Asymptotic Statistics of Random Covering Surfaces
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

A note on the probability of generating alternating or symmetric groups [PDF]
We improve on recent estimates for the probability of generating the alternating and symmetric groups $\mathrm{Alt}(n)$ and $\mathrm{Sym}(n)$. In particular we find the sharp lower bound, if the probability is given by a quadratic in $n^{-1}$. This leads

FI-modules over Noetherian rings [PDF]
FI-modules were introduced by the first three authors to encode sequences of representations of symmetric groups. Over a field of characteristic 0, finite generation of an FI-module implies representation stability for the corresponding sequence of Sn ...

Finding involutions with small support [PDF]
We show that the proportion of permutations $g$ in $S_n$ or $A_n$ such that $g$ has even order and $g^{|g|/2}$ is an involution with support of cardinality at most $\lceil n^\varepsilon \rceil$ is at least a constant multiple of $\varepsilon$. Using this

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

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 ...
