On central endomorphisms of a group [PDF]

open access: yesInternational 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) ‎.

Endomorphisms of fibred groups [PDF]

open access: yesProceedings 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 :

ENDOMORPHISM CONGRUENCES

open access: yesDemonstratio 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.

Principally Quasi-Injective Semimodules

open access: yesمجلة 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.

Enumerating Problems Concerning Endomorphisms of Double Vertex Wheel Graphs

open access: yesJournal of Mathematics
We 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.

The minimal closed monoids for the Galois connection ${\rm End}$-${\rm Con}$ [PDF]

open access: yesMathematica Bohemica
The minimal nontrivial endomorphism monoids $M={\rm End}{\rm Con} (A,F)$ of congruence lattices of algebras $(A,F)$ defined on a finite set $A$ are described.

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

An inequality on polarized endomorphisms

AbstractWe show that assuming the standard conjectures, for any smooth projective varietyXof dimensionnover an algebraically closed field, there is a constant$$c>0$$c>0such that for any positive rational numberrand any polarized endomorphismfofX, we have$$\begin{aligned} \Vert G_r \circ f \Vert \le c \deg (G_r \circ f), \end{aligned}$$‖Gr∘f‖≤cdeg(

On the additive image of zeroth persistent homology

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...
