The purpose of this note is to generalize a result of Gulliksen, Ribenboim and Viswanathan which characterized local group rings when both the ring and the group are commutative.We assume throughout that all rings are associative with identity. If R is a ring we call R local if R/J(R) is a division ring where J(R) denotes the Jacobson radical of R.

Summary: For any integer \(n\neq 0,1\), a group is said to be \(n\)-Bell if it satisfies the law \([x^n,y]=[x,y^n]\). In this paper we prove that every finitely generated locally graded \(n\)-Bell group embeds into the direct product of a finite \(n\)-Bell group and a torsion-free nilpotent group of class \(\leq 2\).

Locally compact transformation groups
Transactions of the American Mathematical Society, 1961In ?1 of this paper it is shown that a variety of conditions implying nice behavior for topological transformation groups are, in the presence of separability, equivalent. In ?2 the continuity properties of the stability subgroups are studied. The conditions of ?1 exclude the line acting on the torus in such a way that each orbit is dense. They exclude

Interconnection Locality and Group Locality
EUROCON 2005 - The International Conference on "Computer as a Tool", 2005The interconnection locality is the behavior of a network around the origin and it is firstly understood as neighborhood. The group locality, which we try to define in this paper, is another point of view on the networks locality, opposite, in some way, to the globality.

Locally compact abelian p-groups
Topology and its Applications, 2019In this interesting and well-written paper the authors study various aspects of \textit{ periodic} locally compact abelian (lca) groups. An lca group \(G\) is called \textit{ periodic} if it is totally disconnected and is a direct union of its compact subgroups.

The group G is locally finite if each of its finitely generated subgroups is finite. Until rather recently the area of locally finite groups entirely belonged to the wilderness of counter-examples; and there absurdly wild behaviour is possible, indeed. What little progress has been made in cultivating some fringes of this wilderness is essentially due ...

Infinite locally dihedral groups as automorphism groups
Ricerche di Matematica, 2014It is well-known that there exist groups which cannot be realized as full automorphism group of any group, obvious examples being the (non-trivial) cyclic groups of odd order and (non-trivial) free groups. It was proved by \textit{D. J. S. Robinson} [Q. J. Math., Oxf. II. Ser.

This paper considers the two following mathematical points. - Characterization of factor systems arising in locally operating representations, - identification of candidates for local splitting and representation groups. The inflation-restriction sequence (or exact homology sequence) is the tool used to discuss these problems some applications and ...
