Automorphisms of the affine Cremona group [PDF]
, 2013 We show that every automorphism of the group Gn := Aut(An) of polynomial automorphisms of complex affine n-space An = Cn is inner up to field automorphisms when restricted to the subgroup TGn of tame automorphisms.

Automorphisms of a finite $p$-group with cyclic Frattini subgroup [PDF]
International Journal of Group Theory, 2018 Let $G$ be a group and $Aut^{Phi}(G)$ denote the group of all automorphisms of $G$ centralizing $G/Phi(G)$ elementwise. In this paper, we characterize the finite $p$-groups $G$ with cyclic Frattini subgroup for which $|Aut^{Phi}(G):Inn(G)|=p$.

Basic automorphisms of cartan foliations covered by fibrations
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2021 Background. This work is devoted to the study of basic automorphisms AB (M,F) groups of Cartan foliations (M,F) covered by fibrations, and to finding sufficient conditions for the existence of a finite-dimensional Lie group structure in AB (M,F) .

Semilattices with a group of automorphisms [PDF]
, 1997 We investigate semilattices expanded by a group F of automorphisms acting as new unary basic operations. We describe up to isomorphism all simple algebras of this kind in case that F is commutative.

Continuous Spectrum of Automorphism Groups and the Infraparticle Problem [PDF]
, 2010 This paper presents a general framework for a refined spectral analysis of a group of isometries acting on a Banach space, which extends the spectral theory of Arveson.

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 ...

Frobenius-like groups as groups of automorphisms [PDF]
, 2014 A finite group FH is said to be Frobenius-like if it has a nontrivial nilpotent normal subgroup F with a nontrivial complement H such that FH/[F,F] is a Frobenius group with Frobenius kernel F/[F,F].

Cluster automorphism groups and automorphism groups of exchange graphs [PDF]
Pacific Journal of Mathematics, 2020 For a coefficient free cluster algebra $\mathcal{A}$, we study the cluster automorphism group $Aut(\mathcal{A})$ and the automorphism group $Aut(E_{\mathcal{A}})$ of its exchange graph $E_{\mathcal{A}}$. We show that these two groups are isomorphic with each other, if $\mathcal{A}$ is of finite type excepting types of rank two and type $F_4$, or if ...
