Counting maximal arithmetic subgroups [PDF]

open access: green, 2005
We study the growth rate of the number of maximal arithmetic subgroups of bounded covolumes in a semi-simple Lie group using an extension of the method due to Borel and Prasad.

Bounds on the Number of Maximal Subgroups of Finite Groups: Applications

open access: yesMathematics, 2022
The determination of bounds for the number of maximal subgroups of a given index in a finite group is relevant to estimate the number of random elements needed to generate a group with a given probability.

Symmetric $1$-designs from $PSL_{2}(q),$ for $q$ a power of an odd prime [PDF]

open access: yesTransactions on Combinatorics, 2021
Let $G = \PSL_{2}(q)$‎, ‎where $q$ is a power of an odd prime‎. ‎Let $M$ be a maximal subgroup of $G$‎. ‎Define $\left\lbrace \frac{|M|}{|M \cap M^g|}‎: ‎g \in G \right\rbrace$ to be the set of orbit lengths of the primitive action of $G$ on the ...

Every Group is a Maximal Subgroup of the Free Idempotent Generated Semigroup over a band [PDF]

open access: yesInternational journal of algebra and computation, 2013
Given an arbitrary group G we construct a semigroup of idempotents (band) BG with the property that the free idempotent generated semigroup over BG has a maximal subgroup isomorphic to G. If G is finitely presented then BG is finite. This answers several

A generalization of the Chermak--Delgado measure on subgroups and its associated lattice [PDF]

open access: yesInternational Journal of Group Theory, 2023
We generalize the Chermak--Delgado measure of a subgroup of a finite group $G$, $\mu(H) = |H||C_{G}(H)|$, and its associated lattice of subgroups with maximal measure. We consider mappings $M$ of the lattice of all subgroups $\mathrm{Sub}(G)$ into itself

Wielandt′s Theorem and Finite Groups with Every Non-nilpotent Maximal Subgroup with Prime Index

open access: yesJournal of Harbin University of Science and Technology, 2023
In order to give a further study of the solvability of a finite group in which every non-nilpotent maximal subgroup has prime index, the methods of the proof by contradiction and the counterexample of the smallest order and a theorem of Wielandt on the ...

Maximal subgroups and PST-groups [PDF]

open access: yesOpen Mathematics, 2013
Abstract A subgroup H of a group G is said to permute with a subgroup K of G if HK is a subgroup of G. H is said to be permutable (resp. S-permutable) if it permutes with all the subgroups (resp. Sylow subgroups) of G. Finite groups in which permutability (resp. S-permutability) is a transitive relation are called PT-groups (resp.

Every group is a maximal subgroup of a naturally occurring free idempotent generated semigroup [PDF]

open access: yes, 2012
The study of the free idempotent generated semigroup IG(E) over a biordered set E has recently received a deal of attention. Let G be a group, let $n\in\mathbb{N}$ with n≥3 and let E be the biordered set of idempotents of the wreath product $G\wr ...

On Maximal Subgroups of Free Idempotent Generated Semigroups [PDF]

open access: yes, 2011
We prove the following results: (1) Every group is a maximal subgroup of some free idempotent generated semigroup. (2) Every finitely presented group is a maximal subgroup of some free idempotent generated semigroup arising from a finite semigroup.

Maximal finite subgroups and minimal classes [PDF]

open access: yesL’Enseignement Mathématique, 2015
We apply Voronoi’s algorithm to compute representatives of the conjugacy classes of maximal finite subgroups of the unit group of a maximal order in some simple \mathbf Q -algebra.
