Lattice theory of torsion classes [PDF]
, 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 $A$.

Advanced Science, EarlyView.The interplay between magnetic ordering and crystal electric field (CEF) excitations plays a pivotal role in defining the low‐energy electrodynamics of quantum materials. By probing the temperature‐dependent THz conductivity in a rare‐earth‐based metallic ferromagnet, we uncover a microscopic connection between localized and itinerant electrons ...

Advances in Mathematics, 2000 The author solves two problems raised by G. Grätzer in 1964, using Priestley duality. For a bounded distributive lattice \(L\), let \(S_k(L)\) (resp. \(S(L))\) denote the lattice of all \(k\)-ary (resp. finitary) ``Boolean functions'' on \(L\), that is, functions \(f: L^k\to L\) such that \(\vec a \theta \vec b\) implies \(f(\vec a) \theta f(\vec b ...

A survey of recent results on congruence lattices of lattices [PDF]
, 2005 We review recent results on congruence lattices of (infinite) lattices. We discuss results obtained with box products, as well as categorical, ring-theoretical, and topological ...

Satisfiability in multi-valued circuits
, 2017 Satisfiability of Boolean circuits is among the most known and important problems in theoretical computer science. This problem is NP-complete in general but becomes polynomial time when restricted either to monotone gates or linear gates.

On Congruence Lattices of Nilsemigroups [PDF]
, 2016 We prove that the congruence lattice of a nilsemigroup is modular if and only if the width of the semigroup, as a poset, is at most two, and distributive if and only if its width is one. In the latter case, such semigroups therefore coincide with the nil

Carbon Energy, EarlyView.Herein, we propose a straightforward and efficacious strategy of surface modification for P2‐type Na0.7Li0.03Mg0.03Ni0.27Mn0.6Ti0.07O2 cathode in high‐voltage Na‐ion batteries. The stable amorphous SiO2 coating layer on the cathode surface contributes to a strong, dense, fluorine and silicon‐rich cathode–electrolyte interphase, which inhibits the side ...

The possible values of critical points between strongly congruence-proper varieties of algebras [PDF]
, 2014 We denote by Conc(A) the semilattice of all finitely generated congruences of an (universal) algebra A, and we define Conc(V) as the class of all isomorphic copies of all Conc(A), for A in V, for any variety V of algebras.

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