Conjugacy classes of affine automorphisms of K^n and linear automorphisms of P^n in the Cremona groups [PDF]

open access: yes, 2006
We describe the conjugacy classes of affine automorphisms in the group $Aut(n,\K)$ (respectively $Bir(\K^n)$) of automorphisms (respectively of birational maps) of $\K^n$.

Endomorphisms of Some Groupoids of Order $k+k^2$

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
Automorphisms and endomorphisms are actively used in various theoretical studies. In particular, the theoretical interest in the study of automorphisms is due to the possibility of representing elements of a group by automorphisms of a certain algebraic ...

Generalized Unitaries and the Picard Group [PDF]

open access: yes, 2005
After discussing some basic facts about generalized module maps, we use the representation theory of the algebra of adjointable operators on a Hilbert B-module E to show that the quotient of the group of generalized unitaries on E and its normal subgroup

New Techniques for SIDH-based NIKE

open access: yesJournal of Mathematical Cryptology, 2020
We consider the problem of producing an efficient, practical, quantum-resistant non-interactive key exchange (NIKE) protocol based on Supersingular Isogeny Diffie-Hellman (SIDH).

Representation of groups by automorphisms of normal topological spaces [PDF]

open access: yesКомпьютерные исследования и моделирование, 2009
The famous fact [3, 5] of existence of an exact representation for any finite group in the form of the full automorphism group of a finite graph was generalize in [4].

Outer automorphism anomalies [PDF]

open access: yesJournal of High Energy Physics, 2022
Abstract We discuss anomalies associated with outer automorphisms in gauge theories based on classical groups, namely charge conjugations for SU(N ) and parities for SO(2r). We emphasize the inequivalence (yet related by a flavor transformation) between two versions of charge conjugation for SU(2k), SO(2r), and E6 symmetries.

Groups of basic automorphisms of chaotic Cartan foliations with Eresmann connection [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика
The purpose of the work is to study the groups of basic automorphisms of chaotic Cartan foliations with Ehresmann connection. Cartan foliations form a category where automorphisms preserve not only the foliation, but also its transverse Cartan geometry ...

Automorphisms of real Lie algebras of dimension five or less [PDF]

open access: yes, 2013
The Lie algebra version of the Krull-Schmidt Theorem is formulated and proved. This leads to a method for constructing the automorphisms of a direct sum of Lie algebras from the automorphisms of its indecomposable components.

Extremal Binary and Ternary Codes of Length 60 with an Automorphism of Order 29 and a Generalization

open access: yesMathematics, 2022
In this paper, all extremal Type I and Type III codes of length 60 with an automorphism of order 29 are classified up to equivalence. In both cases, it has been proven that there are three inequivalent codes.
