Automorphism Groups and Isometries for Cyclic Orbit Codes [PDF]
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]
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 ...

The description of the automorphism groups of finite-dimensional cyclic Leibniz algebras
In the study of Leibniz algebras, the information about their automorphisms (as well as about endomorphisms, derivations, etc.) is very useful. We describe the automorphism groups of finite-dimensional cyclic Leibniz algebras. In particular, we consider

Automorphism group schemes of bielliptic and quasi-bielliptic surfaces [PDF]
Bielliptic and quasi-bielliptic surfaces form one of the four classes of minimal smooth projective surfaces of Kodaira dimension $0$. In this article, we determine the automorphism schemes of these surfaces over algebraically closed fields of arbitrary ...

Relative automorphism groups of right‐angled Artin groups [PDF]
We study the outer automorphism group of a right‐angled Artin group AΓ with finite defining graph Γ . We construct a subnormal series for Out (AΓ) such that each consecutive quotient is either finite, free‐abelian, GL (n,Z) or a Fouxe‐Rabinovitch group ...

Calculating the symmetry of hexamethylcyclohexane
An Euclidean graph associated with a molecule is defined by a weighted graph with adjacency matrix. Balasubramanian (1995) computed the Euclidean graphs and their automorphism groups for benzene, eclipsed and staggered forms of ethane, and eclipsed and ...

Automorphism groups of finite topological rank [PDF]
We offer a criterion for showing that the automorphism group of an ultrahomogeneous structure is topologically 2-generated and even has a cyclically dense conjugacy class.

On the automorphism groups of relatively free groups of infinite rank: a survey
The paper is intended to be a survey on some topics within the framework of automorphisms of a relatively free groups of infinite rank. We discuss such properties as tameness, primitivity, small index, Bergman property, and so on.

Finite $2$-groups of class $2$ with a specific automorphism group [PDF]
In this paper we determine all finite $2$-groups of class $2$ in which every automorphism of order $2$ leaving the Frattini subgroup elementwise fixed is inner.
