Automorphisms and Definability (of Reducts) for Upward Complete Structures

open access: yesMathematics, 2022
The Svenonius theorem establishes the correspondence between definability of relations in a countable structure and automorphism groups of these relations in extensions of the structure.

On complete congruence lattices of complete lattices [PDF]

open access: yesTransactions of the American Mathematical Society, 1991
The lattice of all complete congruence relations of a complete lattice is itself a complete lattice. In this paper, we characterize this lattice as a complete lattice. In other words, for a complete lattice L L

ON COMPLETE CONGRUENCE LATTICES OF COMPLETE MODULAR LATTICES [PDF]

open access: yesInternational Journal of Algebra and Computation, 1991
The lattice of all complete congruence relations of a complete lattice is itself a complete lattice. In 1988, the second author announced the converse: every complete lattice L can be represented as the lattice of complete congruence relations of some complete lattice K.

Completely representable lattices [PDF]

open access: yesAlgebra universalis, 2012
It is known that a lattice is representable as a ring of sets iff the lattice is distributive. CRL is the class of bounded distributive lattices (DLs) which have representations preserving arbitrary joins and meets. jCRL is the class of DLs which have representations preserving arbitrary joins, mCRL is the class of DLs which have representations ...

Complete Congruence Lattices of Complete Distributive Lattices

open access: yesJournal of Algebra, 1995
The authors deal with the question of whether every complete lattice \(L\) is isomorphic to the lattice of complete congruence relations of a suitable complete lattice \(K\). They prove that \(K\) can always be chosen as a complete distributive lattice. In fact, they prove a more general result: Let \(m\) be a regular cardinal \(>\aleph_ 0\). Every \(m\

Reflective Full Subcategories of the Category of L-Posets

open access: yesAbstract and Applied Analysis, 2012
This paper focuses on the relationship between L-posets and complete L-lattices from the categorical view. By considering a special class of fuzzy closure operators, we prove that the category of complete L-lattices is a reflective full subcategory of ...

FUZZY CONNECTIONS AND COMPLETENESS IN COMPLETE RESIDUATED LATTICES [PDF]

open access: yesKorean Journal of Mathematics, 2013
Summary: In this paper, we investigate the properties of fuzzy Galois (dual Galois, residuated, dual residuated) connections in a complete residuated lattice \(L\).

“Complete-simple” distributive lattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1993
It is well known that the only simple distributive lattice is the two-element chain. We can generalize the concept of a simple lattice to complete lattices as follows: a complete lattice is complete-simple if it has only the two trivial complete congruences.
