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 ...

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

Using situation lattices in sensor analysis [PDF]

open access: yes, 2009
Highly sensorised systems present two parallel challenges: how to design a sensor suite that can efficiently and cost-effectively support the needs of given services; and to extract the semantically relevant interpretations, or "situations", from the ...

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

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.

Characterizations of rings and modules by means of lattices [PDF]

open access: yes, 1965
PhDIn this thesis we study the relationship between the lattice of submodules and the algebraic structure of a module. The key remark in our study will be the fact that the homomorphisms between two independent submadules of a module can be ...
