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.

The Haagerup property is not invariant under quasi‐isometry

Bulletin of the London Mathematical Society, Volume 58, Issue 11, November 2026.
Abstract Using the work of Cornulier–Valette and Whyte (see Appendix A for the latter), we show that neither the Haagerup property nor weak amenability is invariant under quasi‐isometry of finitely generated groups. Appendix B shows, using the same examples, that the same holds for vanishing of the equivariant Lp$L^p$‐compression.

Automorphisms of the generalized cluster complex

The American Journal of Combinatorics
We exhibit a dihedral symmetry in the generalized cluster complex defined by Fomin and Reading. Together with diagram symmetries, they generate the automorphism group of the complex.

On the Andreadakis conjecture of the automorphism group of a free group (Geometry, Algebra and Combinatorics in Transformation group theory) [PDF]

, 2018
In this article, we show that the third subgroup of the Andreadakis-Johnson filtration of the automorphism group of a free group coincides with the the third group of the lower central series of the IA-automorphism ...

Artificial Intelligence‐Driven Inverse Design of Singlet Fission Candidates in the Acene family

Advanced Science, Volume 13, Issue 59, 23 October 2026.
In this work, we describe an AI‐driven inverse design platform predicting S1 and T1 energies across acenes with high accuracy. Using Hammett σ constants as descriptors and RNN models coupled with optimization algorithms, it efficiently explores ≈1014 structures, uncovering novel SF candidates from benzene to pentacene.

A description of an automorphism of a split metacyclic p-group [PDF]

, 2010
A map on a group is not necessarily an automorphism on the group. In this paper we determined the necessary and sufficient conditions of a map on a split metacyclic p-group to be an automorphism, where we only considered p as an odd prime number.

AUTOMORPHISM OF CYCLIC GROUPS

Journal 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.

Algebraic reflexivity of isometry groups and automorphism groups of some operator structures [PDF]

, 2013
We establish the algebraic re exivity of three isometry groups of operator structures: The group of all surjective isometries on the unitary group, the group of all surjective isometries on the set of all positive invertible operators equipped with ...

On the characterization of Danielewski surfaces by their automorphism group

, 2022
In this note we show that if the automorphism group of a normal affine surface S is isomorphic to the automorphism group of a Danielewski surface, then S is isomorphic to the normalization of a Danielewski ...
