Frobenius groups as groups of automorphisms [PDF]
Proceedings of the American Mathematical Society, 2010 We show that if G F H GFH is a double Frobenius group with “upper” complement H H of order q q such that C G ( H ) C_G(H) is nilpotent of class c c , then G G is ...

Classification of quantum graphs on M2 and their quantum automorphism groups [PDF]
Journal of Mathematics and Physics, 2021 Motivated by the string diagrammatic approach to undirected tracial quantum graphs by Musto et al. [J. Math. Phys. 59(8), 081706 (2018)], in the former part of this paper, we diagrammatically formulate directed nontracial quantum graphs by Brannan et al.

The automorphism groups of the profinite braid groups [PDF]
American Journal of Mathematics, 2019 :In this paper we determine the automorphism groups of the profinite braid groups with four or more strings in terms of the profinite Grothendieck-Teichm\"uller group.

Right‐angled Artin groups as finite‐index subgroups of their outer automorphism groups [PDF]
Bulletin of the London Mathematical Society, 2022 We prove that every right‐angled Artin group occurs as a finite‐index subgroup of the outer automorphism group of another right‐angled Artin group. We furthermore show that the latter group can be chosen in such a way that the quotient is isomorphic to ...

Automorphism groups of the constituent graphs of integral distance graphs
AKCE International Journal of Graphs and Combinatorics, 2023 In this paper, we consider the automorphism groups of Cayley graphs which are a basis of a complete Boolean algebra of strongly regular graphs, one of such graph is the integral distance graph [Formula: see text] The automorphism groups of the integral ...

Serre’s Property (FA) for automorphism groups of free products [PDF]
Journal of group theroy, 2019 We provide some necessary and some sufficient conditions for the automorphism group of a free product of (freely indecomposable, not infinite cyclic) groups to have Property (FA).

Automorphism groups of polycyclic-by-finite groups and arithmetic groups [PDF]
, 2005 We show that the outer automorphism group of a polycyclic-by-finite group is an arithmetic group. This result follows from a detailed structural analysis of the automorphism groups of such groups. We use an extended version of the theory of the algebraic

AUTOMORPHISM GROUPS OF FREE GROUPS [PDF]
Journal of the Australian Mathematical Society, 2008 Abstract This note contains some remarks on generating pairs for automorphism groups of free groups. There has been significant use of electronic assistance. Little of this is used to verify the results.

Automorphism groups of graph covers and uniform subset graphs
AKCE International Journal of Graphs and Combinatorics, 2018 Hofmeister considered the automorphism groups of antipodal graphs through the exploration of graph covers. In this note we extend the exploration of automorphism groups of distance preserving graph covers.

Automorphism groups of quandles and related groups [PDF]
Monatshefte für Mathematik (Print), 2017 In this paper we study various questions concerning automorphisms of quandles. For a conjugation quandle $$Q=\mathrm{Conj}(G)$$Q=Conj(G) of a group G we determine several subgroups of $$\mathrm{Aut}(Q)$$Aut(Q) and find necessary and sufficient conditions
