On the trace of permuting tri-derivations on rings
Математичні Студії, 2022 In the paper we examined the some effects of derivation, trace of permuting tri-derivation and endomorphism on each other in prime and semiprime ring. Let $R$ be a $2,3$-torsion free prime ring and $F:R\times R\times R\rightarrow R$ be a permuting tri ...

Infinitesimally stable endomorphisms [PDF]
Transactions of the American Mathematical Society, 1994 For diffeomorphisms infinitesimal stability is well-known to be an open property that is equivalent to structural stability. The author uses an idea of K. Odani to show that for endomorphisms this property is not open. It is shown also that if an endomorphism \(f\) belongs to the interior of the set of infinitesimally stable ones, then \(f\) is ...

Rings whose additive endomorphisms are ring endomorphisms [PDF]
Bulletin of the Australian Mathematical Society, 1992 A ring R is said to be an AE-ring if every endomorphism of its additive group R+ is a ring endomorphism. Clearly, the zero ring on any abelian group is an AE-ring. In a recent article, Birkenmeier and Heatherly characterised the so-called standard AE-lings, that is, the non-trivial AE-rings whose maximal 2-subgroup is a direct summand.

On central endomorphisms of a group [PDF]
International Journal of Group Theory, 2015 Let Γ be a normal subgroup of the full automorphism group Aut(G) of a group G , and assume that Inn(G)≤Γ . An endomorphism σ of G is said to be {\it Γ -central} if σ induces the the identity on the factor group G/C G (Γ) .

Selecciones Matemáticas, 2022 In this paper, we show a way to characterize the R-automorphisms of formal power series on several indeterminates and with coefficients over a commutative ring with identity, R.

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.

Cogenerator endomorphism rings [PDF]
Proceedings of the American Mathematical Society, 1971 If R R is a ring and P P is a finitely generated projective right R R -module, what properties of R R does the R R -endomorphism ring of P P inherit? Rosenberg and Zelinsky have shown that if R R is quasi-Frobenius, and P

Principally Quasi-Injective Semimodules
مجلة بغداد للعلوم, 2019 In this work, the notion of principally quasi- injective semimodule is introduced, discussing the conditions needed to get properties and characterizations similar or related to the case in modules.

On periodic points of free inverse monoid endomorphisms
, 2012 It is proved that the periodic point submonoid of a free inverse monoid endomorphism is always finitely generated. Using Chomsky's hierarchy of languages, we prove that the fixed point submonoid of an endomorphism of a free inverse monoid can be ...

Enumerating Problems Concerning Endomorphisms of Double Vertex Wheel Graphs
Journal of MathematicsWe can define six classes of endomorphisms on a graph, and they always form a chain based on set inclusion. The concepts of endomorphism type and endomorphism spectrum were introduced by Böttcher and Knauer in 1992.
