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 :

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.

Ranks of Monoids of Endomorphisms of a Finite Undirected Path [PDF]
, 2020 In this paper, we study the widely considered endomorphisms and weak endomorphisms of a finite undirected path from monoid generators perspective. Our main aim is to determine the ranks of the monoids wEnd Pn and End Pn of all weak endomorphisms and all ...

Localized endomorphisms of graph algebras [PDF]
, 2011 Endomorphisms of graph C*-algebras are investigated. A combinatorial ap- proach to analysis of permutative endomorphisms is developed. Then invertibility criteria for localized endomorphisms are given.

An inequality on polarized endomorphisms
Archiv der Mathematik, 2022 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(

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

Varieties characterized by their endomorphisms [PDF]
, 2014 We show that two varietes X and Y with isomorphic endomorphism semigroups are isomorphic up to field automorphism if one of them is affine and contains a copy of the affine line.

On the additive image of zeroth persistent homology
Transactions 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 ...

Endomorphisms of graph algebras
, 2012 We initiate a systematic investigation of endomorphisms of graph C*-algebras C* (E), extending several known results on endomorphisms of the Cuntz algebras O-n.
