Symmetries of 2-lattices and second order accuracy of the Cauchy-Born model [PDF]

open access: yes, 2013
We show that the Cauchy-Born model of a single-species 2-lattice is second order if the atomistic and continuum kinematics are connected in a novel way. Our proof uses a generalization to 2-lattices of the point symmetry of Bravais lattices. Moreover, by

Filters in Strong BI-Algebras and Residuated Pseudo-SBI-Algebras

open access: yesMathematics, 2020
The concept of basic implication algebra (BI-algebra) has been proposed to describe general non-classical implicative logics (such as associative or non-associative fuzzy logic, commutative or non-commutative fuzzy logic, quantum logic).

Agents and rough sets [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2014
Rough set theory gives approximation models of complex knowledge structure. Agents are not present in the definition of the rough sets. Now we will show that a set of conflicting agents or active set can be used to model inconsistent decision in rough ...

Internal structure of hexagonal skyrmion lattices in cubic helimagnets [PDF]

open access: yes, 2016

Fuzzy ideals and fuzzy congruences of co-residuated lattices [PDF]

open access: yesJournal of Hebei University of Science and Technology
In order to expand the theory of fuzzy logic algebra, the fuzzy ideals and fuzzy congruences of co-residuated lattices and their interrelationships were studied.

Collective modes of vortex lattices in two-component Bose–Einstein condensates under synthetic gauge fields

open access: yesNew Journal of Physics, 2019
We study collective modes of vortex lattices in two-component Bose–Einstein condensates subject to synthetic magnetic fields in mutually parallel or antiparallel directions. By means of the Bogoliubov theory with the lowest-Landau-level approximation, we

Reduction theory of lattices and its applications to cryptography and coding theory

open access: yes, 2023
Lattices are fascinating mathematical structures that unify the fields of geometry and number theory. In recent years, lattices have risen to prominence outside of pure mathematical study, taking on a more practical application in the fields of ...

Neutrosophic Multigroups and Applications

open access: yesMathematics, 2019
In recent years, fuzzy multisets and neutrosophic sets have become a subject of great interest for researchers and have been widely applied to algebraic structures include groups, rings, fields and lattices.

Higher-Order Theories for Doubly Curved Laminated Lattice and Honeycomb Structures [PDF]

open access: yes14th WCCM-ECCOMAS Congress, 2021
A collocation model based on a Generalized Differential Quadrature Method (GDQM) is proposed for the dynamic analysis of anisotropic curved laminated structures with a central lattice core and different external constraints. The theory is based on the Equivalent Single Layer (ESL) approach, together with higher-order kinematic assumptions.

Fuzzy Soft Sets and Fuzzy Soft Lattices [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2012
The theory of soft sets was introduced by Molodtsov in 1999 in order to deal with uncertainties. In this paper, the notion of fuzzy soft lattice is defined and some related properties are derived, which extends the notion of a fuzzy lattice to include ...
