Automorphisms of Some Magmas of Order $k+k^2$

Известия Иркутского государственного университета: Серия "Математика", 2018
This paper is devoted to the study of automorphisms of finite magmas and to the representation of the symmetric permutation group $ S_k $ and some of its subgroups by automorphism groups of finite magmas.

Topological rigidity of automorphism systems

Nantong Daxue xuebao. Ziran kexue ban
This paper studies the automorphism actions of countable discrete groups on the étale equivalence relations on compact metric spaces. First, the notion of continuous strong orbit equivalence for automorphism systems is introduced and it is proved that ...

Automorphisms of K-groups I [PDF]

Journal of Algebra, 2018
This work is a continuation of Automorphisms of $K$-groups I, P. Flavell, preprint. The main object of study is a finite $K$-group $G$ that admits an elementary abelian group $A$ acting coprimely. For certain group theoretic properties $\mathcal P$, we study the $AC_{G}(A)$-invariant $\mathcal P$-subgroups of $G$.

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.

Embeddings of Automorphism Groups of Free Groups into Automorphism Groups of Affine Algebraic Varieties

Proceedings of the Steklov Institute of Mathematics, 2023
Abstract For every integer $$n>0$$ , we construct a new infinite series of rational affine algebraic varieties such that their automorphism groups contain the automorphism group

Finite groups of automorphisms of infinite groups, I

Journal of Algebra, 1981
AbstractThis paper studies Aut A in the case in which A is an infinite abelian group and Aut A is finite. Information is obtained about the structure of Aut A including the description of a large normal subgroup. Aut A is completely characterized when it is abelian. Its order is determined when it is dihedral or generalized quaternion.

Automorphism groups of some pure braid groups

Topology and its Applications, 2012
We find finite presentations for the automorphism group of the Artin pure braid group and the automorphism group of the pure braid group associated to the full monomial group.

Non-abelian extensions and Wells exact sequences of Hom-pre-Lie algebras

Mathematics Open
In this paper, we investigate non-abelian extensions of Hom-pre-Lie algebras and extensibility of pairs of automorphisms about non-abelian extensions.
