On 7‐adic Galois representations for elliptic curves over Q$\mathbb {Q}$

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract In recent years, significant progress has been made on Mazur's Program B, with many authors beginning a systematic classification of all possible images of p$p$‐adic Galois representations attached to elliptic curves over Q$\mathbb {Q}$. Currently, the classification is only complete for p∈{2,3,13,17}$p \in \lbrace 2,3,13,17\rbrace$.

Endomorphisms of the Riordan group

, 2019
We state a characterization of endomorphisms of the Riordan group by means of suitable maps, acting on power series, that we name the coordinates of the endomorphism.

An example exploration of the T.Yoshida theorem(T.Yoshida定理的一个实例探讨)

Zhejiang Daxue xuebao. Lixue ban
Combining the relevant theories of finite group theory and elementary number theory, and using the properties of congruence equations, a class of non-abelian groups of order 16p2 is determined. By exploring the orders of elements and generating relations,

Endomorphism and Automorphism Graphs

Let $G$ be a group. The directed endomorphism graph, \dend of $G$ is a directed graph with vertex set $G$ and there is a directed edge from the vertex `$a$' to the vertex `$\, b$' $(a \neq b) $ if and only if there exists an endomorphism on $G$ mapping $a$ to $b$.

Endomorphism near-rings of 𝑝-groups generated by the automorphism and inner automorphism groups [PDF]

Proceedings of the American Mathematical Society, 1993
The purpose of this paper is to investigate the equality of the endomorphism near-rings generated by the automorphism group and inner automorphism group of a nonabelian p p

Sylow subgroups and the number of irreducible characters of degrees divisible by a prime p$p$

Bulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.
Abstract Let G$G$ be a finite group and p$p$ be a prime. We establish an upper bound for the derived length of a Sylow p$p$‐subgroup of G$G$ in terms of the number of irreducible characters of G$G$ whose degrees are divisible by p$p$. We also prove that if B$B$ is a p$p$‐block of a finite p$p$‐solvable group G$G$ with defect group D$D$, then the ...

Endomorphisms of the Cuntz algebras

, 2012
This mainly expository article is devoted to recent advances in the study of dynamical aspects of the Cuntz algebras O_n, n<infty, via their automorphisms and, more generally, endomorphisms.

Entropy for endomorphisms of LCA groups [PDF]

, 2012
We introduce a modified version of the entropy defined for locally compact Abelian groups by Peters. This approach allows us to work with endomorphisms instead of working with automorphisms.

On the theories classified by an étendue

Bulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.
Abstract We give a model‐theoretic characterisation of the geometric theories classified by étendues—the ‘locally localic’ topoi. They are the theories where each model is determined, syntactically and semantically, by any witness of a fixed collection of formulae.
