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.

Projective modules with semilocal endomorphism ring [PDF]

, 2002
It is proved that a projective left R-module P with semilocal endomorphism ring is finitely generated if and only if hdim(P) = hdim((P/J(P)).It is proved that a projective left R-module P with semilocal endomorphism ring is finitely generated if and only

Baer Endomorphism Rings and Closure Operators

, 1978
A Baer ring is a ring in which every right (and left) annihilator ideal is generated by an idempotent. Generalizing quite naturally from the fact that the endomorphism ring of a vector space is a Baer ring, Wolfson [5; 6] investigated questions such as ...

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 ...

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)

Endomorphisms of profinite groups

Groups, Geometry, and Dynamics, 2014
We obtain some general restrictions on the continuous endomorphisms of a profinite group G under the assumption that G has only finitely many open subgroups of each index (an assumption which automatically holds, for instance, if
