Maximal subgroups of the modular and other groups [PDF]

open access: yesJournal of group theroy, 2018
In 1933 B. H. Neumann constructed uncountably many subgroups of SL2⁢(ℤ){{\rm SL}_{2}(\mathbb{Z})} which act regularly on the primitive elements of ℤ2{\mathbb{Z}^{2}}. As pointed out by Magnus, their images in the modular group PSL2⁢(ℤ)≅C3*C2{{\rm PSL}_{2}

The number of maximal subgroups and probabilistic generation of‎ ‎finite groups [PDF]

open access: yesInternational Journal of Group Theory, 2020
In this survey we present some significant bounds for the‎ ‎number of maximal subgroups of a given index of a finite group‎. ‎As a‎ ‎consequence‎, ‎new bounds for the number of random‎ ‎generators needed to generate a finite $d$-generated group with high‎

Maximal subgroups of finite groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
In finite groups maximal subgroups play a very important role. Results in the literature show that if the maximal subgroup has a very small index in the whole group then it influences the structure of the group itself.

Association of Maximal Extent of Resection of Contrast-Enhanced and Non-Contrast-Enhanced Tumor With Survival Within Molecular Subgroups of Patients With Newly Diagnosed Glioblastoma.

open access: yesJAMA Oncology, 2020
Importance Per the World Health Organization 2016 integrative classification, newly diagnosed glioblastomas are separated into isocitrate dehydrogenase gene 1 or 2 (IDH)-wild-type and IDH-mutant subtypes, with median patient survival of 1.2 and 3.6 years,

Maximal subgroups of groups of intermediate growth [PDF]

open access: yesAdvances in Mathematics, 2016
Finding the number of maximal subgroups of infinite index of a finitely generated group is a natural problem that has been solved for several classes of “geometric” groups (linear groups, hyperbolic groups, mapping class groups, etc).

Words for maximal Subgroups of Fi24‘

open access: yesOpen Chemistry, 2019
Group Theory is the mathematical application of symmetry to an object to obtain knowledge of its physical properties. The symmetry of a molecule provides us with the various information, such as - orbitals energy levels, orbitals symmetries, type of ...

The conjugacy class ranks of $M_{24}$ [PDF]

open access: yesInternational Journal of Group Theory, 2017
$M_{24}$ is the largest Mathieu sporadic simple group of order $244 823 040 = 2^{10} {cdot} 3^3 {cdot} 5 {cdot} 7 {cdot} 11 {cdot} 23$ and contains all the other Mathieu sporadic simple groups as subgroups.

A semilattice of varieties of completely regular semigroups [PDF]

open access: yesMathematica Bohemica, 2020
Completely regular semigroups are unions of their (maximal) subgroups with the unary operation within their maximal subgroups. As such they form a variety whose lattice of subvarieties is denoted by $\mathcal L(\mathcal C\mathcal R)$.

Algebraic subgroups of the plane Cremona group over a perfect field [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2021
We show that any infinite algebraic subgroup of the plane Cremona group over a perfect field is contained in a maximal algebraic subgroup of the plane Cremona group.
