Varieties of K-lattices

Fuzzy Sets and Systems, 2022
In this paper we deal with varieties of commutative residuated lattices that arise from a specific kind of construction: the twist-productof a lattice.

Varieties of bounded K-lattices [PDF]

Fuzzy Sets and Systems, 2022
In this paper we continue to study varieties of K-lattices, focusing on their bounded versions. These (bounded) commutative residuated lattices arise from a specific kind of construction: the twist-product of a lattice.

Artificial kagome lattices of Shockley surface states patterned by halogen hydrogen-bonded organic frameworks [PDF]

Nature Communications
Artificial electronic kagome lattices may emerge from electronic potential landscapes using customized structures with exotic supersymmetries, benefiting from the confinement of Shockley surface-state electrons on coinage metals, which offers a flexible ...

Topological mechanical metamaterial for robust and ductile one-way fracturing [PDF]

Nature Communications
Fracturing is unavoidable and threatens the reliability and functionality of materials. Therefore, regulating the propagation of cracks in a predictable and ductile manner is of paramount importance.

“Polymerization” of Bimerons in Quasi-Two-Dimensional Chiral Magnets with Easy-Plane Anisotropy [PDF]

Nanomaterials
We re-examine the internal structure of bimerons, which are stabilized in easy-plane chiral magnets and represent coupled states of two merons with the same topological charge |1/2| but with opposite vorticity and the polarity.

Order Filter Model for Minuscule Plücker Relations [PDF]

Discrete Mathematics & Theoretical Computer Science, 2020
The Plücker relations which define the Grassmann manifolds as projective varieties are well known. Grass-mann manifolds are examples of minuscule flag manifolds.

Stone Commutator Lattices and Baer Rings

Discussiones Mathematicae - General Algebra and Applications, 2022
In this paper, we transfer Davey‘s characterization for κ -Stone bounded distributive lattices to lattices with certain kinds of quotients, in particular to commutator lattices with certain properties, and obtain related results on prime, radical ...

Strictly join irreducible varieties of residuated lattices [PDF]

, 2022
We study (strictly) join irreducible varieties in the lattice of subvarieties of residuated lattices. We explore the connections with well-connected algebras and suitable generalizations, focusing in particular on representable varieties.

On tractability and congruence distributivity [PDF]

Logical Methods in Computer Science, 2007
Constraint languages that arise from finite algebras have recently been the object of study, especially in connection with the Dichotomy Conjecture of Feder and Vardi.

Varieties of Distributive Rotational Lattices [PDF]

, 2013
summary:A rotational lattice is a structure $\langle L;\vee ,\wedge , g\rangle $ where $L=\langle L;\vee ,\wedge \rangle $ is a lattice and $g$ is a lattice automorphism of finite order.
