Infinitesimal Stability of Anosov Endomorphisms [PDF]

, 1996
It is well known that infinitesimal stability of diffeomorphisms is an open property. But infinitesimal stability of endomorphisms is not an open property.

About uniform distribution of four-dimensional torus

Lietuvos Matematikos Rinkinys, 2002
Results on the uniform distribution of ergodic endomorphisms on the four-dimensional torus are obtained. They extend previous results [1] for the case when the characteristic polynomial of matrix V may be reducible.

The join of split graphs whose completely regular endomorphisms form a monoid

Open Mathematics, 2017
In this paper, completely regular endomorphisms of the join of split graphs are investigated. We give conditions under which all completely regular endomorphisms of the join of two split graphs form a monoid.

Classification of finite potent endomorphisms [PDF]

, 2014
[EN]The aim of this work is to offer a family of invariants that allows us to classify finite potent endomorphisms on arbitrary vector spaces, generalizing the classification of endomorphisms on finite-dimensional vector spaces.

A characterization of singular endomorphisms of a barrelled Pták space

International Journal of Mathematics and Mathematical Sciences, 1982
The concept of topological divisor of zero has been extended to endomorphisms of a locally convex topological vector space (LCTVS). A characterization of singular endomorphisms, similar to that of Yood [1], is obtained for endomorphisms of a barrelled ...

Endomorphisms of fibred groups [PDF]

Proceedings of the Edinburgh Mathematical Society, 1989
A collection = {Gα|α∈A} of proper subgroups Gα of a group G is a fibration of G ifIt is of geometric interest to associate two semigroups to a group G with fibration :

SOME IDENTITIES INVOLVING ENDOMORPHISMS OF PRIME RINGS [PDF]

Journal of Algebraic Systems
In this paper we will extend some results on the commutativity of quotient rings proved in [1] and [11]. However, we will consider endomorphisms instead of derivations and generalized derivations, which is sufficient to obtain good results.

ENDOMORPHISM CONGRUENCES

Demonstratio Mathematica, 1995
The notion of endomorphism congruence considered in this paper has a close connection with the notion of result. To say most generally, results are fractions such that their numerators are elements of a certain linear space while their denominators are injective endomorphisms of that space.

Quasicompact and Riesz endomorphisms of Banach algebras [PDF]

, 2005
Let B be a unital commutative semi-simple Banach algebra. We study endomorphisms of B which are also quasicompact operators or Riesz operators. Clearly compact and power compact endomorphisms are Riesz and hence quasicompact.
