Approximation of induced automorphisms and special automorphisms [PDF]
Proceedings of the American Mathematical Society, 1978 A class of measure-preserving invertible point transformations which admit approximations is defined. If T is an automorphism which admits an approximation, conditions are given such that an induced automorphism and a special automorphism over T again ...

Nonlinear Equivariant Automorphisms [PDF]
, 1997 We show that the natural representation of SL 3 \Theta SL 5 \Theta SL 13 allows nonlinear equivariant automorphisms; more exactly, the group of polynomial automorphisms on C commuting with the simple SL 3 \Theta SL 5 \Theta SL 13 - action is ...

On Automorphisms of Line-graphs
European Journal of Combinatorics, 1980 This paper generalizes some results on hypergraph reconstruction due to \textit{C. Berge} [C. R. Acad. Sci., Paris, Ser. A 274, 1783-1786 (1972; Zbl 0236.05129)] and \textit{J.C.Fournier} [Proc. 1rst Working Sem. Hypergraphs, Columbus 1972, Lecture Notes Math. 411, 95-98 (1974; Zbl 0302.05113)].

Metric properties of outer space [PDF]
We define metrics on Culler-Vogtmann space, which are an analogue of the Teichmuller metric and are constructed using stretching factors. In fact the metrics we study are related, one being a symmetrised version of the other.

A hitchhiker's guide to endomorphisms and automorphisms of Cuntz algebras [PDF]
, 2021 We present a broad selection of results on endomorphisms and automorphisms of the Cuntz algebras $mathcal{O}_n$ that have been obtained in the last decades.

Automorphisms of free braided nonassociative algebras of rank 2
Қарағанды университетінің хабаршысы. Математика сериясыWe prove the elementary reducibility of any nonaffine automorphism of a free nonassociative algebra of rank two over an arbitrary field. Using this result establish a property of automorphisms of this algebra that will be needed in later. We then derive

The classification of modular Lie superalgebras of type M
Open Mathematics, 2015 The natural filtration of the infinite-dimensional simple modular Lie superalgebra M over a field of characteristic p > 2 is proved to be invariant under automorphisms by discussing ad-nilpotent elements.

Time Automorphisms on C*-Algebras
Mathematics, 2015 Applications of fractional time derivatives in physics and engineering require the existence of nontranslational time automorphisms on the appropriate algebra of observables.
