Mixability of Finite Groups

Random Structures &Algorithms, Volume 67, Issue 4, December 2025.
ABSTRACT A finite group G$$ G $$ is mixable if a product of random elements, each chosen independently from two options, can distribute uniformly on G$$ G $$. We present conditions and obstructions to mixability. We show that 2‐groups, the symmetric groups, the simple alternating groups, several matrix and sporadic simple groups, and most finite ...

On supersolvability of finite groups with $mathbb P$-subnormal subgroups [PDF]

International Journal of Group Theory, 2013
In this paper we have found systems of subgroups in a finite group which $Bbb P$-subnormality guarantees supersolvability of the whole group.

Mortality Prediction by Bedside Rectus Femoris Muscle Ultrasound for Sarcopenia Diagnosis in Liver Cirrhosis

United European Gastroenterology Journal, Volume 13, Issue 10, Page 1936-1945, December 2025.
ABSTRACT Background Sarcopenia is common in patients with liver cirrhosis and is an independent predictor of morbidity and mortality. This prospective study assessed the performance of rectus femoris muscle (RFM) ultrasound in patients with liver cirrhosis to identify those at risk for sarcopenia as defined by the combination of low muscle mass and low

Exponential and weakly exponential subgroups of finite groups [PDF]

International Journal of Group Theory
Sabatini [L. Sabatini, Products of subgroups, subnormality, and relative orders of elements, Ars Math. Contemp., 24 no. 1 (2024) 9 pp.] defined a subgroup $H$ of $G$ to be an exponential subgroup if $x^{|G:H|} \in H$ for all $x \in G$, in which case we ...

Groups in which Sylow subgroups and subnormal subgroups permute

Illinois Journal of Mathematics, 2003
A finite group is called a PST-group if its subnormal subgroups permute with its Sylow subgroups. It is shown that if \(G\) is a PST-group and \(H_1/K_1\) and \(H_2/K_2\) are isomorphic Abelian chief factors of \(G\) with \(H_1H_2\subseteq G'\), then these factors are \(G\)-isomorphic (Theorem 2).

Subnormal subgroups in free groups, their growth and cogrowth

, 2017
In this paper, the author (1) compare subnormal closures of finite sets in a free group F; (2) obtains the limit for the series of subnormal closures of a single element in F; (3) proves that the exponential growth rate (exp.g.r.) $\lim_{n\to \infty ...

Canadian Endocrinologists′ Perspectives on Treatment With Thyroid Hormone Substitutions in Euthyroid and Hypothyroid Patients: A 2023 THESIS Questionnaire Survey

Clinical Endocrinology, Volume 103, Issue 5, Page 739-748, November 2025.
ABSTRACT Objective The practice of treating hypothyroid and euthyroid patients with thyroid hormones varies between countries, as observed in the recent surveys of European thyroid experts, THESIS. As part of the THESIS initiative, we investigated Canadian endocrinologists′ perspectives on this topic, focusing on combination therapy with either ...

Theoretical Researches about u-Maximal Subgroups and Its Applications in Charactering IntuG

Journal of Chemistry, 2019
Let G be a finite group and u be the class of all finite supersoluble groups. A supersoluble subgroup U of G is called u-maximal in G if for any supersoluble subgroup V of G containing U, V=U.

Stable equivalence relations on 4‐manifolds

Proceedings of the London Mathematical Society, Volume 131, Issue 5, November 2025.
Abstract Kreck's modified surgery gives an approach to classifying smooth 2n$2n$‐manifolds up to stable diffeomorphism, that is, up to connected sum with copies of Sn×Sn$S^n \times S^n$. In dimension 4, we use a combination of modified and classical surgery to study various stable equivalence relations which we compare to stable diffeomorphism.
