AUTOMORPHISM OF CYCLIC GROUPS [PDF]

open access: yesJournal of Mountain Area Research
In this article, we will study cyclic groups  A.  We have found a class of cyclic groups A which are not determined with their automorphism groups in CQ.

AUTOMORPHISM GROUPS OF MAPS, SURFACES AND SMARANDACHE GEOMETRIES [PDF]

open access: yes, 2011
Automorphism groups survey similarities on mathematical systems, which appear nearly in all mathematical branches, such as those of algebra, combinatorics, geometry, · · · and theoretical physics, theoretical chemistry, etc..

Most switching classes with primitive automorphism groups contain graphs with trivial groups [PDF]

open access: yes, 2015
The operation of switching a graph Gamma with respect to a subset X of the vertex set interchanges edges and non-edges between X and its complement, leaving the rest of the graph unchanged.

Automorphism groups of the constituent graphs of integral distance graphs

open access: yesAKCE 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 ...

Automorphism groups of rational surfaces [PDF]

open access: yes, 2020
In this paper, we consider automorphism groups of rational surfaces which admit cuspidal anticanonical curves and have certain nontrivial automorphisms.

Automorphism groups of compact complex surfaces [PDF]

open access: yes, 2021
We study automorphism groups and birational automorphism groups of compactcomplex surfaces. We show that the automorphism group of such surface $X$ isalways Jordan, and the birational automorphism group is Jordan unless $X$ isbirational to a product of ...

On the endomorphism semigroups of extra-special $p$-groups and automorphism orbits [PDF]

open access: yesInternational Journal of Group Theory, 2022
For an odd prime $p$ and a positive integer $n$, it is well known that there are two types of extra-special $p$-groups of order $p^{2n+1}$, first one is the Heisenberg group which has exponent $p$ and the second one is of exponent $p^2$.

On automorphism groups of Toeplitz subshifts

open access: yesDiscrete Analysis, 2017
On automorphism groups of Toeplitz subshifts, Discrete Analysis 2017:11, 19 pp. A discrete dynamical system is a space $X$ with some kind of structure, together with a map $\sigma\colon X\to X$ that preserves the structure.

1-Designs from the group PSL2(59) and their automorphism groups [PDF]

open access: yesMathematics Interdisciplinary Research, 2018
In this paper, we consider the projective special linear group PSL2(59) and construct some 1-designs by applying the Key-Moori method on  PSL2(59). Moreover, we obtain parameters of these designs and their automorphism groups.
