Derangements in intransitive groups

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract Let G$G$ be a nontrivial permutation group of degree n$n$. If G$G$ is transitive, then a theorem of Jordan states that G$G$ has a derangement. Equivalently, a finite group is never the union of conjugates of a proper subgroup. If G$G$ is intransitive, then G$G$ may fail to have a derangement, and this can happen even if G$G$ has only two ...

Gorenstein algebras presented by quadrics [PDF]

open access: yes, 2011
We establish restrictions on the Hilbert function of standard graded Gorenstein algebras with only quadratic relations. Furthermore, we pose some intriguing conjectures and provide evidence for them by proving them in some cases using a number of ...

Representations of constant socle rank for the Kronecker algebra [PDF]

open access: yesForum mathematicum, 2016
Inspired by recent work of Carlson, Friedlander and Pevtsova concerning modules for p-elementary abelian groups E r {E_{r}} of rank r over a field of characteristic p > 0 {p>0} , we introduce the notions of modules with constant d-radical rank and ...

Pros and Cons of Bernini's Design for the Louvre: Monumentality Without Dome, Pediment or Free‐Standing Column and Its Drawbacks

open access: yesJAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT In the 17th‐century Louvre expansion project, many architects used free‐standing columns, domes and large pediments for its east elevation. These elements helped give the elevation, over 150 m wide, the monumentality the court wanted, while also providing the appropriate articulation. Bernini was probably the only architect who did not use any

Iterated socles and integral dependence in regular rings [PDF]

open access: yes, 2014
Let $R$ be a formal power series ring over a field, with maximal ideal $\mathfrak m$, and let $I$ be an ideal of $R$ such that $R/I$ is Artinian. We study the iterated socles of $I$, that is the ideals which are defined as the largest ideal $J$ with $J ...

Revision of the Tribe Bythinini (Staphylinidae, Pselaphinae) From Korea With Molecular Phylogeny

open access: yesZoologica Scripta, Volume 55, Issue 1, Page 131-144, January 2026.
ABSTRACT Although three genera of Bythinini are known from East Asia, Bythoxenites Jeannel, Bryaxis Kugelann and Tychobythinus Ganglbauer, only Bryaxis has been reported in Korea, and no phylogenetic research has been conducted. We report new records of the genus Tychobythinus in Korea and describe T. rasiligulus sp. n.

The $lambda$-super socle of the ring of continuous functions [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2017
The concept of $lambda$-super socle of $C(X)$, denoted by $S_lambda(X)$ (i.e., the set of elements of $C(X)$  such that the cardinality of their cozerosets are  less than $lambda$, where $lambda$  is  a regular cardinal number with  $lambdaleq |X|$)  is ...

Socle finiteness of the local cohomology

open access: yesRocky Mountain Journal of Mathematics, 2011
Let \(R\) be a commutative local noetherian ring. Finiteness properties of local cohomology modules over \(R\) are among the basic topics of local cohomology theory. One of the main question is as follows ``Let \(I\) be an ideal of \(R\). Is the socle of \(H^n_I(R)\) finitely generated?'' A positive answer to this question for all regular local ring ...

When do pseudo‐Gorenstein rings become Gorenstein?

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract We discuss the relationship between the trace ideal of the canonical module and pseudo‐Gorensteinness. In particular, under certain mild assumptions, we show that every positively graded domain that is both pseudo‐Gorenstein and nearly Gorenstein is Gorenstein. As an application, we clarify the relationships among nearly Gorensteinness, almost
