On ideals of a skew lattice

open access: yes, 2012
Ideals are one of the main topics of interest to the study of the order structure of an algebra. Due to their nice properties, ideals have an important role both in lattice theory and semigroup theory.

Some algebraic aspects of mesoprimary decomposition

open access: yes, 2018
Recent results of Kahle and Miller give a method of constructing primary decompositions of binomial ideals by first constructing "mesoprimary decompositions" determined by their underlying monoid congruences.

Lattice theory of torsion classes [PDF]

open access: yes, 2018
The aim of this paper is to establish a lattice theoretical framework to study the partially ordered set $\operatorname{\mathsf{tors}} A$ of torsion classes over a finite-dimensional algebra $A$.

Quivers of monoids with basic algebras

open access: yes, 2011
We compute the quiver of any monoid that has a basic algebra over an algebraically closed field of characteristic zero. More generally, we reduce the computation of the quiver over a splitting field of a class of monoids that we term rectangular monoids (

Linear representations of regular rings and complemented modular lattices with involution

open access: yes, 2016
Faithful representations of regular $\ast$-rings and modular complemented lattices with involution within orthosymmetric sesquilinear spaces are studied within the framework of Universal Algebra.

Selective Crystal Growth and Optical Responses of 2H and 3R Polytypes in van der Waals Polar Insulator α‐In2Se3

open access: yesAdvanced Optical Materials, EarlyView.
Selective growth protocols are established to obtain high‐quality bulk single crystals of the 2H and 3R polytypes of the vdW polar insulator α‐In2Se3, together with rapid, non‐destructive phase‐identification methods. Combined optical transmission and absolute reflectivity measurements, supported by DFT calculations, reveal distinct polytype‐dependent ...

Heat Capacity Measurements and Thermodynamic Assessment of the Y2O3–Ta2O5 System

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT Phase equilibria in the Y2O3–Ta2O5 system play an important role in the development of new materials for thermal barrier coating (TBC) applications, with higher thermal stability resulting in more efficient gas turbines with reduced exhaust gas emissions.

Phase equilibria in the Li2O‒MnOx system

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Phase equilibria in the Li2O‒MnOx system was experimentally investigated under air condition and inert atmosphere (Ar). The experimental investigations for selected compositions of isothermally heat‐treated samples were performed using X‐ray diffraction and scanning electron microscopy/energy dispersive X‐ray spectroscopy. Differential thermal

The modular automorphisms of quotient modular curves

open access: yesMathematika, Volume 72, Issue 1, January 2026.
Abstract We obtain the modular automorphism group of any quotient modular curve of level N$N$, with 4,9∤N$4,9\nmid N$. In particular, we obtain some unexpected automorphisms of order 3 that appear for the quotient modular curves when the Atkin–Lehner involution w25$w_{25}$ belongs to the quotient modular group. We also prove that such automorphisms are

A note on local formulae for the parity of Selmer ranks

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 10, Page 3112-3132, October 2025.
Abstract In this note, we provide evidence for a certain ‘twisted’ version of the parity conjecture for Jacobians, introduced in prior work of Dokchitser, Green, Konstantinou and the author. To do this, we use arithmetic duality theorems for abelian varieties to study the determinant of certain endomorphisms acting on p∞$p^\infty$‐Selmer groups.
