Inclusions of characterized subgroups [PDF]
Topology and its Applications, 2017 A subgroup H of R is characterized if H=tau_R:={x in R: u_n x --> 0 mod Z} for some sequence u in R. Given two sequences u and v in R, we find conditions under which tau_u(R) is contained or not in tau_v(R).

Dirichlet sets vs Characterized subgroups [PDF]
Topology and its Applications, 2017 A subset A of the circle group T is a Dirichlet set if there exists an increasing sequence u = (un) n∈N 0 in N such that unx → 0 uniformly on A. In particular, A is contained in the subgroup tu(T) := {x ∈ T : unx → 0}, which is the subgroup of T ...

On T-sequences and characterized subgroups
Topology and its Applications, 2010 Let X be a compact metrizable abelian group and u={un} be a sequence in its dual group X∧. Set su(X)={x:(un,x)→1} and T0H={(zn)∈T∞:zn→1}. Let G be a subgroup of X.

, 2015 Let T = R / Z be the written additively circle group and u = (un) be a sequence of integers. Many authors in various areas of Mathematics gave their attention to the following subgroups of T and their subsets t u( T ) = { x ∈ T | unx → 0 } .

A Subgroup of Latently Mycobacterium tuberculosis Infected Individuals Is Characterized by Consistently Elevated IgA Responses to Several Mycobacterial Antigens [PDF]
Mediators of Inflammation, 2015 Elevated antibody responses to Mycobacterium tuberculosis antigens in individuals with latent infection (LTBI) have previously been linked to an increased risk for progression to active disease. Studies in the field focussed mainly on IgG antibodies.

On the Characterization of Antineutrosophic Subgroup
Advances in Mathematical Physics, 2023 This article gives some essential scopes to study the characterizations of the antineutrosophic subgroup and antineutrosophic normal subgroup. Again, several theories and properties have been mentioned which are essential for analyzing their mathematical framework. Moreover, their homomorphic properties have been discussed.

Characterizing subgroup perfect codes by 2-subgroups
Designs, Codes and Cryptography, 2023 A perfect code in a graph $Γ$ is a subset $C$ of $V(Γ)$ such that no two vertices in $C$ are adjacent and every vertex in $V(Γ)\setminus C$ is adjacent to exactly one vertex in $C$. Let $G$ be a finite group and $C$ a subset of $G$. Then $C$ is said to be a perfect code of $G$ if there exists a Cayley graph of $G$ admiting $C$ as a perfect code.

Normal cryptogroups with an associate subgroup [PDF]
, 1997 summary:Let $S$ be a semigroup. For $a,x\in S$ such that $a=axa$, we say that $x$ is an associate of $a$. A subgroup $G$ of $S$ which contains exactly one associate of each element of $S$ is called an associate subgroup of $S$.

A characterization of groups with isomorphic subgroups [PDF]
Proceedings of the American Mathematical Society, 1972 The concept of normalizer is generalized to derive a characterization of groups G which contain a proper subgroup isomorphic to G .

Anosov subgroups: dynamical and geometric characterizations [PDF]
European Journal of Mathematics, 2017 We study infinite covolume discrete subgroups of higher rank semisimple Lie groups, motivated by understanding basic properties of Anosov subgroups from various viewpoints (geometric, coarse geometric and dynamical). The class of Anosov subgroups constitutes a natural generalization of convex cocompact subgroups of rank one Lie groups to higher rank ...
