Groups with Anomalous Automorphisms

Journal of Algebra, 1996
Let \(G\) be a group. The set \(\Aut_{nn}G\) of all automorphisms of \(G\) fixing every non-normal subgroup of \(G\) is a normal subgroup of the full automorphism group \(\Aut G\) of \(G\). Of course, \(\Aut_{nn}G\) contains the group \(P\Aut G\) of all power automorphisms of \(G\), and the structure of groups \(G\) such that \(P\Aut G\neq\Aut_{nn}G ...

Finite Vertex Bi-Primitive 2-Arc Transitive Graphs Admitting a Two-Dimensional Linear Group

IEEE Access, 2019
A graph is said to be vertex bi-primitive, if it is a bipartite graph, and the setwise stabilizer of its automorphism group acts primitively on two bi-parts.

Bounded Automorphisms of Groups

Journal of Algebra, 1994
Let \(G\) be the fundamental group of a graph of groups (in the sense of Bass-Serre theory). Such a group has a natural length function and thus a corresponding notion of bounded subgroups and bounded automorphisms. The general result of this paper is that an automorphism of \(G\) is bounded if and only if it is induced by isomorphisms of vertex groups

A note on one-parameter groups of automorphisms

International Journal of Mathematics and Mathematical Sciences, 1990
Let {αt:t∈R} and {βt:t∈R} be two commuting one-parameter groups of ∗-automorphisms of a von Neumann algebra M such that αt+α−t=βt+β−t for all t∈R. The purpose of this note is to provide a simple and short proof of the central decomposition result: αt=βt ...

Automorphisms of solvable groups [PDF]

Proceedings of the American Mathematical Society, 1962
It is important to note that in both these statements only the existence of integers t(p, n) and m(p) is claimed. The only specific information known is that in(2) =2, m (3) =2, and mi(5) = 3 (see [1 ]) . Even upper bounds for the values of t(p, n) and m(p) are not known to us.

Automorphisms of graph groups

Journal of Algebra, 1989
Given a graph \(\Gamma=(V,E)\), the graph group \(F\langle\Gamma\rangle\) is the group with presentation \(\langle V\mid [E]\rangle\), where \([E]\) denotes the set of commutators \(\{[a,b]\mid\{a,b\}\in E\}\). The graph group \(F\langle\Gamma\rangle\) is modeled to be a group analog of the graph algebra K(\(\Gamma)\) generated as a free associative ...

Upper bounds of orders of automorphism groups of leafless metric graphs

AKCE International Journal of Graphs and Combinatorics
We prove a tropical analogue of the theorem of Hurwitz: A leafless metric graph of genus [Formula: see text] has at most 12 automorphisms when g = 2 and [Formula: see text] automorphisms when [Formula: see text].
