On the automorphism groups of Frobenius groups [PDF]
Communications in Algebra, 2020 This is one of a series papers which aim towards to solve the problem of determining automorphism groups of Frobenius groups. This one solves the problem in the case where the Frobenius kernels are elementary abelian and Frobenius complements are cyclic.

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.

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).

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 and Isometries for Cyclic Orbit Codes [PDF]
Advances in Mathematics of Communications, 2021 We study orbit codes in the field extension \begin{document}$ \mathbb{F}_{q^n} $\end{document}. First we show that the automorphism group of a cyclic orbit code is contained in the normalizer of the Singer subgroup if the orbit is generated by a subspace

Hilbert schemes of lines and conics and automorphism groups of Fano threefolds [PDF]
, 2016 We discuss various results on Hilbert schemes of lines and conics and automorphism groups of smooth Fano threefolds of Picard rank 1. Besides a general review of facts well known to experts, the paper contains some new results, for instance, we give a ...

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

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.

ON THE GROWTH OF GROUPS AND AUTOMORPHISMS [PDF]
International Journal of Algebra and Computation, 2005 We consider the growth functions βΓ(n) of amalgamated free products Γ = A *C B, where A ≅ B are finitely generated, C is free abelian and |A/C| = |A/B| = 2. For every d ∈ ℕ there exist examples with βΓ(n) ≃ nd+1βA(n). There also exist examples with βΓ(n) ≃ en. Similar behavior is exhibited among Dehn functions.
