Completely contractive representations of some doubly generated antisymmetric operator algebras. [PDF]
, 1998 Contractive weak star continuous representations of the Fourier binest algebra (of Katavolos and Power) are shown to be completely contractive. The proof depends on the approximation of by semicrossed product algebras and on the complete contractivity of

Braiding groups of automorphisms and almost-automorphisms of trees
Canadian Journal of Mathematics, 2023 AbstractWe introduce “braided” versions of self-similar groups and Röver–Nekrashevych groups, and study their finiteness properties. This generalizes work of Aroca and Cumplido, and the first author and Wu, who considered the case when the self-similar groups are what we call “self-identical.” In particular, we use a braided version of the Grigorchuk ...

Groups with some central automorphisms fixing the central kernel quotient [PDF]
Journal of Mahani Mathematical Research, 2023 Let $G$ be a group. An automorphism $\alpha$ of a group $G$ is called a central automorphism, if $x^{-1}x^{\alpha}\in Z(G)$ for all $x\in G$.

On automorphisms of biproducts [PDF]
Communications in Algebra, 2016 We study certain subgroups of the full group of Hopf algebra automorphisms of a biproduct. In the process interesting subgroups of certain permutation groups come into play.

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

Groups of basic automorphisms of chaotic Cartan foliations with Eresmann connection [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамикаThe 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 ...

Twist automorphisms and Poisson structures [PDF]
, 2023 We introduce (quantum) twist automorphisms for upper cluster algebras and cluster Poisson algebras with coefficients. Our constructions generalize the twist automorphisms for quantum unipotent cells.

On the operator equation α+α−1=β+β−1
International Journal of Mathematics and Mathematical Sciences, 1986 Let α,β be ∗-automorphisms of a von Neumann algebra M satisfying the operator equation α+α−1=β+β−1. In this paper we use new techniques (which are useful in noncommutative situations as well) to provide alternate proofs of the results:- If α,β commute ...
