A Linguistic-Valued Weighted Aggregation Operator to Multiple Attribute Group Decision Making with Quantative and Qualitative Information [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2008
In selecting an optional alternative in an environment of multiple attribute group decision making, different attributes of the alternative are often considered as with quantitative and qualitative information.

Towards prediction of ordered phases in rechargeable battery chemistry via group–subgroup transformation

open access: yesnpj Computational Materials, 2021
The electrochemical thermodynamic and kinetic characteristics of rechargeable batteries are critically influenced by the ordering of mobile ions in electrodes or solid electrolytes. However, because of the experimental difficulty of capturing the lighter

Topological lattice-ordered groups [PDF]

open access: yesPacific Journal of Mathematics, 1979
Several types of hulls and completions of lattice ordered groups have been obtained by algebraic methods. In this paper is laid some groundwork for the application of topological and uniform-space concepts to the same end by setting forth those links—topological, algebraic and semantic— between a topological lattice ordered group H and a topologically ...

$\alpha$-Projectable and laterally $\alpha$-complete Archimedean lattice-ordered groups with weak unit via topology [PDF]

open access: yesCategories and General Algebraic Structures with Applications
Let $\bf{W}$ be the category of Archimedean lattice-ordered groups with weak order unit, $\bf{Comp}$ the category of compact Hausdorff spaces, and $\mathbf{W} \xrightarrow{Y} \mathbf{Comp}$ the Yosida functor, which represents a $\bf{W}$-object $A$ as ...

Kernels in Lattice-Ordered Groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
It is shown that a lattice-ordered group has a largest representaba convex l l -subgroup and a largest normal valued convex l l -subgroup. Other kernels are discussed.

Origin of coherent structures in a discrete chaotic medium [PDF]

open access: yes, 1999
Using as an example a large lattice of locally interacting Hindmarsh-Rose chaotic neurons, we disclose the origin of ordered structures in a discrete nonequilibrium medium with fast and slow chaotic oscillations.

Large off-diagonal magnetoelectricity in a triangular Co2+-based collinear antiferromagnet

open access: yesNature Communications, 2023
Magnetic toroidicity is an uncommon type of magnetic structure in solid-state materials. Here, we experimentally demonstrate that collinear spins in a material with R-3 lattice symmetry can host a significant magnetic toroidicity, even parallel to the ...

The conjugacy problem and related problems in lattice-ordered groups [PDF]

open access: yes, 2005
We study, from a constructive computational point of view, the techniques used to solve the conjugacy problem in the "generic" lattice-ordered group Aut(R) of order automorphisms of the real line.

open access: yesTransactions of the American Mathematical Society, 1983
The authors characterize the finitely generic abelian lattice-ordered groups and make application of this characterization to specific examples.

Nuclearity of semigroup C*-algebras and the connection to amenability [PDF]

open access: yes, 2012
We study C*-algebras associated with subsemigroups of groups. For a large class of such semigroups including positive cones in quasi-lattice ordered groups and left Ore semigroups, we describe the corresponding semigroup C*-algebras as C*-algebras of ...
