A Van Benthem Characterization Result for Distribution-Free Logics

open access: yesLogics
This article contributes to recent results in the model theory of distribution-free logics (which include a Goldblatt-Thomason theorem and a development of their Sahlqvist theory) by lifting van Benthem’s characterization result for modal logic to the ...

Residuated bilattices [PDF]

open access: yes, 2012
We introduce a new product bilattice con- struction that generalizes the well-known one for interlaced bilattices and others that were developed more recently, allowing to obtain a bilattice with two residuated pairs as a certain kind of power of an ...

Relational groupoids and residuated lattices

open access: yesEPiC Series in Computing, 2018
A quite general order-theoretical approach to implicative structures leads to consider implicative groupoids, which form a wide class of algebras including residuated lattices and their reasonable generalizations. Implicative groupoids find out to be special instances of suitable relational systems and are objects of categories, semicategories and ...

Open projections do not form a right residuated lattice

open access: yes
The lattice of open projection of a C*-algebra has a partial monoid structure on compatible elements. However, this does not extend to a total right residuated operation.

ON L-FUZZY INTERIOR (CLOSURE) SPACES

open access: yesJournal of New Theory, 2016
Abstaract−The aim of this paper is to introduce the concept of L-fuzzy interior (closure) spaces and the L-fuzzy topological space in a complete residuated lattice. We study some relationships among those structures.

Matrices over residuated lattices [PDF]

open access: yes, 2014
Residuated lattices simultaneously generalise lattice-ordered groups and the structures used to model various many-valued logics (e.g., Boolean algebras, Heyting algebras and MV-algebras).

Stable Topology on Ideals for Residuated Lattices

open access: yesTransactions on Fuzzy Sets and Systems
Residuated lattices are the major algebraic counterpart of logics without contraction rule, as they are more generalized logic systems including important classes of algebras such as Boolean algebras, MV-algebras, BL-algebras, Stonean residuated lattices,

Representation of Prelinear Residuated Algebras

open access: yes, 2008
— In 1998, Hájek established a representation theorem of BL-algebrs as all subdirect products of linear BL-algebrs. We establish a similar result for the much wider class of prelinear residuated algebras, in which neither the lattice structure nor the ...
