Nilpotency in endomorphism rings [PDF]

Proceedings of the American Mathematical Society, 1974
Nil subrings of the endomorphism ring of a module with finite Krull dimension sequence are nilpotent. This includes the case of a module with finite Krull dimension as well as noetherian modules. The method used is to embed the endomorphism ring, modulo a nilpotent ideal, in the endomorphism ring of an artinian object of a Grothendieck category.

Polynomial identities for quivers via incidence algebras

Bulletin of the London Mathematical Society, Volume 58, Issue 5, May 2026.
Abstract We show that the path algebra of a quiver satisfies the same polynomial identities (PI) of an algebra of matrices, if any. In particular, the algebra of n×n$n\times n$ matrices is PI‐equivalent to the path algebra of the oriented cycle with n$n$ vertices.

Descending Endomorphisms of Some Families of Groups

, 2023
A descending endomorphism of a group is an endomorphism that induces a corresponding endomorphism in every homomorphic image of the group. Descending endomorphisms of Abelian groups are power maps, and, in particular, those of finite Abelian groups as ...

Polymatroidal tilings and the Chow class of linked projective spaces

Bulletin of the London Mathematical Society, Volume 58, Issue 5, May 2026.
Abstract Linked projective spaces are quiver Grassmannians of constant dimension one of certain quiver representations, called linked nets, over certain quivers, called Zn$\mathbb {Z}^n$‐quivers. They were recently introduced as a tool for describing schematic limits of families of divisors.

Endomorphism spectra of graphs

Discrete Mathematics, 1992
Consider graphs \(G,H\) and a mapping \(f:V(G) \to V(H)\). Suppose that \(f\) is a homomorphism of \(G\) to \(H\), i.e., that any two vertices \(u,v\) in \(f(V(G))\), for which the sets \(f^{-1} (u)\) and \(f^{-1}(v)\) are joined in \(G\) by at least one edge, are adjacent in \(H\). If also conversely, for any two vertices \(u,v \in f(V(G))\) which are

Endomorphisms of Finite Symmetric Inverse Semigroups

The supersingular endomorphism ring problem given one endomorphism

IACR Communications in Cryptology
Given a supersingular elliptic curve E and a non-scalar endomorphism α of E, we prove that the endomorphism ring of E can be computed in classical time about disc(Z[α])^1/4, and in quantum subexponential time, assuming the generalised Riemann hypothesis.

Extensible endomorphisms of compact groups

, 2023
We show that the endomorphisms of a compact connected group that extend to endomorphisms of every compact overgroup are precisely the trivial one and the inner automorphisms; this is an analogue, for compact connected groups, of results due to Schupp and
