On extending endomorphisms to automorphisms

International Journal of Mathematics and Mathematical Sciences, 1988
A monic endomorphism of a structure A can be extended to an automorphism of a larger structure A*. We investigate which properties are preserved by this process.

Some External Characterizations of SV-Rings and Hereditary Rings

International Journal of Mathematics and Mathematical Sciences, 2007
We introduce a new class of rings which we call AI-rings. By applying this property to endomorphism rings, we give characterizations of semi-Artinian V-rings and hereditary rings.

New Results about Quadratic Functional Equation on Semigroups

Annales Mathematicae Silesianae
Let S be a semigroup, let (H, +) be a uniquely 2-divisible, abelian group and let φ, ψ be two endomorphisms of S that need not be involutive. In this paper, we express the solutions f : S → H of the following quadratic functional equation f(xφ(y))+f(ψ(y)

Jordan Normal Forms of Endomorphisms of Vector Bundles over Curves and Applications to Moduli Space Automorphisms

Axioms
Let X be a compact connected Riemann surface of genus g≥2 and let E be a holomorphic vector bundle of rank n over X. The compactness and connectedness of X imply that the characteristic polynomial of any holomorphic endomorphism φ∈H0(X,End(E)) has ...

Endomorphism Rings in Cryptography.

, 2011
La cryptographie est devenue indispensable afin de garantir la sécurité et l'intégrité des données transitant dans les réseaux de communication modernes. Ces deux dernières décennies, des cryptosystèmes très efficaces, sûr et riches en fonctionnalités ont été construits à partir de variétés abéliennes définies sur des corps finis. Cette thèse contribue
