Recognition of subgroups of direct products of hyperbolic groups

open access: yes, 2003
We give examples of direct products of three hyperbolic groups in which there cannot exist an algorithm to decide which finitely presented subgroups are ...

Research of the assortment and information support of medical products and cosmetics

open access: yesФармацевтичний журнал, 2022
An urgent problem of the contemporary domestic pharmaceutical market is the availability of a large number of products and goods that are not registered as medicines in the prescribed manner, but declare in different ways the medicinal properties and ...

Nonsolvable Groups Whose Degrees of All Proper Subgroups Are the Direct Products of at Most Two Prime Numbers

open access: yesJournal of Mathematics, 2022
Huppert and Manz have determined the nonsolvable groups whose character degrees are products of at most two prime numbers. In this paper, we change the condition from “degrees of a group are products of at most two prime divisors” to “degrees of all ...

Normal Subgroup of Product of Groups [PDF]

open access: yesFormalized Mathematics, 2011
Let I be a non empty set, let F be a group-like multiplicative magma family of I, and let i be an element of I. Note that F (i) is group-like. Let I be a non empty set, let F be an associative multiplicative magma family of I, and let i be an element of I. Observe that F (i) is associative.

Outer automorphism groups of graph products: subgroups and quotients [PDF]

open access: yesPacific Journal of Mathematics, 2019
We show that the outer automorphism groups of graph products of finitely generated abelian groups satisfy the Tits alternative, are residually finite, their so-called Torelli subgroups are finitely generated, and they satisfy a dichotomy between being ...

PRODUCTS OF PARTIAL NORMAL SUBGROUPS [PDF]

open access: yes, 2015
We show that the product of two partial normal subgroups of a locality (in the sense of Chermak) is again a partial normal subgroup. This generalizes a theorem of Chermak and fits into the context of building a local theory of localities.

G-Groups and Biuniform Abelian Normal Subgroups [PDF]

open access: yesAdvances in Group Theory and Applications, 2016
We prove a weak form of the Krull-Schmidt Theorem concerning the behavior of direct-product decompositions of $G$-groups, biuniform abelian $G$-groups, $G$-semidirect products and the $G$-set $Hom(H,A)$. Here $G$ and $A$ are groups and $H$ is a $G$-group.

Lifting automorphisms of subgroups of direct products of cyclic $p$-groups [PDF]

open access: yesInternational Journal of Group Theory
Let $\Gamma$ be a finite group. A subgroup $H$ of $\Gamma$ is called ``fully liftable" in $\Gamma$ if every automorphism of $H$ is the restriction of an automorphism of $\Gamma$.

RP-HPLC-Based Flavonoid Profiling Accompanied with Multivariate Analysis: An Efficient Approach for Quality Assessment of Houttuynia cordata Thunb Leaves and Their Commercial Products

open access: yesMolecules, 2023
Chemical profiling for quality monitoring and evaluation of medicinal plants is gaining attention. This study aims to develop an HPLC method followed by multivariate analysis to obtain HPLC profiles of five specific flavonoids, including rutin (1 ...
