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,

Finite groups whose maximal subgroups of even order are MSN-groups

open access: yesOpen Mathematics, 2022
A finite group GG is called an MSN-group if all maximal subgroups of the Sylow subgroups of GG are subnormal in GG. In this article, we investigate the structure of finite groups GG such that GG is a non-MSN-group of even order in which every maximal ...

Designs from maximal subgroups and conjugacy classes of $\mathrm{PSL}(2,q)$, $q$ odd [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2023
In this paper, using a method of construction of $1$-designs which are not necessarily symmetric, introduced by Key and Moori, we determine a number of $1$-designs with interesting parameters from the maximal subgroups and the conjugacy classes of ...

A new algorithm to compute fuzzy subgroups of a finite group

open access: yesAIMS Mathematics, 2023
The enumeration of fuzzy subgroups is a complex problem. Several authors have computed results for special instances of groups. In this paper, we present a novel algorithm that is designed to enumerate the fuzzy subgroups of a finite group.

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 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 Restriction Principle and Commuting Families of Toeplitz Operators on the Unit Ball [PDF]

open access: yes, 2018
On the unit ball B^n we consider the weighted Bergman spaces H_\lambda and their Toeplitz operators with bounded symbols. It is known from our previous work that if a closed subgroup H of \widetilde{\SU(n,1)} has a multiplicity-free restriction for the ...

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.

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.
