On the Endomorphism Algebra of Specht Modules in Even Characteristic [PDF]

open access: yes, 2023
Over fields of characteristic $2$, Specht modules may decompose and there is no upper bound for the dimension of their endomorphism algebra. A classification of the (in)decomposable Specht modules and a closed formula for the dimension of their ...

Nilradicals of skew Hurwitz series of rings

open access: yesLe Matematiche, 2015
‎For a ring endomorphism α of a ring R, ‎Krempa called α a rigid endomorphism if aα(a)=0 implies a = 0 for a in R. ‎A ring R is called rigid if there exists a rigid endomorphism of R.

On the Multidimensional Limit Theorem for Endomorphisms of the Euclidean Space [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2015
Nearly optimal refinement of the earlier estimates of the convergence rate in the multidimensional central limit theorem for sums of functions of the trajectories of endomorphisms of the s-dimensional Euclidean space was performed.

About the Algebraic Yuzvinski Formula

open access: yesTopological Algebra and its Applications, 2015
The Algebraic Yuzvinski Formula expresses the algebraic entropy of an endomorphism of a finitedimensional rational vector space as the Mahler measure of its characteristic polynomial.

A birational description of the minimal exponent

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract We give a description of the minimal exponent of a hypersurface using higher direct images of suitably twisted sheaves of log forms on a log resolution.

A generalisation of Cameron's base size conjecture

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract Let G⩽Sym(Ω)$G\leqslant {\rm Sym}(\Omega)$ be a finite transitive permutation group with point stabiliser H$H$. A base for G$G$ is a subset of Ω$\Omega$ whose pointwise stabiliser is trivial, and the minimal cardinality of a base is called the base size of G$G$, denoted by b(G,Ω)$b(G, \Omega)$. Equivalently, b(G,Ω)$b(G, \Omega)$ is the minimal

Structure of a linear endomorphism [PDF]

open access: yes, 2022
Given an n-dimensional vector space V over a field K, it is proved that if f is an endomorphism of V whose characteristic polynomial has its n roots in K, then f has a Jordan canonical form.

The join of split graphs whose completely regular endomorphisms form a monoid

open access: yesOpen Mathematics, 2017
In this paper, completely regular endomorphisms of the join of split graphs are investigated. We give conditions under which all completely regular endomorphisms of the join of two split graphs form a monoid.

Heights on ‘hybrid orbits’ in Shimura varieties

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We prove the ‘hybrid conjecture’ which is a common generalisation of the André–Oort conjecture and the André–Pink–Zannier conjecture, in the case of Shimura varieties of abelian type.
