Mobius Group Generated by Two Elements of Order 2, 4, and Reduced Quadratic Irrational Numbers

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
The construction of circuits for the evolution of orbits and reduced quadratic irrational numbers under the action of Mobius groups have many applications like in construction of substitution box (s-box), strong-substitution box (s.s-box), image ...

Hypermaps Over Non-Abelian Simple Groups and Strongly Symmetric Generating Sets [PDF]

open access: yes, 2023
A generating pair x, y for a group G is said to be symmetric if there exists an automorphism φx,y of G inverting both x and y, that is, xφx,y = x−1 and yφx,y = y−1.

Graph automaton groups [PDF]

open access: yes, 2021
In this paper we define a way to get a bounded invertible automaton starting from a finite graph. It turns out that the corresponding automaton group is regular weakly branch over its commutator subgroup, contains a free semigroup on two elements and is ...

Commuting involution graphs for [(A)\tilde]n [PDF]

open access: yes, 2006
In this article we consider the commuting graphs of involution conjugacy classes in the affine Weyl group A~n. We show that where the graph is connected the diameter is at most 6.

Curve graphs for Artin–Tits groups of type B, A∼ and C∼ are hyperbolic

open access: yesTransactions of the London Mathematical Society, Volume 8, Issue 1, Page 151-173, December 2021., 2021
Abstract The graph of irreducible parabolic subgroups is a combinatorial object associated to an Artin–Tits group A defined so as to coincide with the curve graph of the (n+1)‐times punctured disk when A is Artin's braid group on (n+1) strands. In this case, it is a hyperbolic graph, by the celebrated Masur–Minsky's theorem.

Deforming cubulations of hyperbolic groups

open access: yesJournal of Topology, Volume 14, Issue 3, Page 877-912, September 2021., 2021
Abstract We describe a procedure to deform cubulations of hyperbolic groups by ‘bending hyperplanes’. Our construction is inspired by related constructions like Thurston's Mickey Mouse example, walls in fibred hyperbolic 3‐manifolds and free‐by‐Z groups, and Hsu–Wise turns.

(Un)distorted stabilisers in the handlebody group

open access: yesJournal of Topology, Volume 14, Issue 2, Page 460-487, June 2021., 2021
Abstract We study geometric properties of stabilisers in the handlebody group. We find that stabilisers of meridians are undistorted, while stabilisers of primitive curves or annuli are exponentially distorted for large enough genus.

Remark on subgroup intersection graph of finite abelian groups

open access: yesOpen Mathematics, 2020
Let G be a finite group. The subgroup intersection graph Γ(G)\text{Γ}(G) of G is a graph whose vertices are non-identity elements of G and two distinct vertices x and y are adjacent if and only if |〈x〉∩〈y〉|>1|\langle x\rangle \cap \langle y\rangle

The intersection graph of graded submodules of a graded module

open access: yesOpen Mathematics, 2022
In this article, we introduce and study the intersection graph of graded submodules of a graded module. Let MM be a left GG-graded RR-module. We define the intersection graph of GG-graded RR-submodules of MM, denoted by Γ(G,R,M)\Gamma \left(G,R,M), to be

Generalized Munn rings

open access: yesOpen Mathematics, 2022
Generalized Munn rings exist extensively in the theory of rings. The aim of this note is to answer when a generalized Munn ring is primitive (semiprimitive, semiprime and prime, respectively).
