Convergence Classes of L‐Filters in (L, M)‐Fuzzy Topological Spaces
An (L, M)‐fuzzy topological convergence structure on a set X is a mapping which defines a degree in M for any L‐filter (of crisp degree) on X to be convergent to a molecule in LX. By means of (L, M)‐fuzzy topological neighborhood operators, we show that the category of (L, M)‐fuzzy topological convergence spaces is isomorphic to the category of (L, M ...

Preserving Filtering Unification by Adding Compatible Operations to Some Heyting Algebras [PDF]
We show that adding compatible operations to Heyting algebras and to commutative residuated lattices, both satisfying the Stone law ¬x ⋁ ¬¬x = 1, preserves filtering (or directed) unification, that is, the property that for every two unifiers there is a ...

Epistemic Updates on Algebras [PDF]
We develop the mathematical theory of epistemic updates with the tools of duality theory. We focus on the Logic of Epistemic Actions and Knowledge (EAK), introduced by Baltag-Moss- Solecki, without the common knowledge operator.

On completeness of reducibility candidates as a semantics of strong normalization [PDF]
This paper defines a sound and complete semantic criterion, based on reducibility candidates, for strong normalization of theories expressed in minimal deduction modulo \`a la Curry.

Big Data Mining: a Computer-Oriented Method of Working with the Semantics of Assertions
When analyzing large amounts of data with the involvement of experts of subject domain, the problem of knowledge representation arises, this problem lies in describing the semantic content of judgments with their subsequent formalization, automated ...

Dyck algebras, interval temporal logic and posets of intervals [PDF]
We investigate a natural Heyting algebra structure on the set of Dyck paths of the same length. We provide a geometrical description of the operations of pseudocomplement and relative pseudocomplement, as well as of regular elements. We also find a logic-

A Note on Regular De Morgan Semi-Heyting Algebras
The purpose of this note is two-fold. Firstly, we prove that the variety RDMSH1 of regular De Morgan semi-Heyting algebras of level 1 satisfies Stone identity and present (equational) axiomatizations for several subvarieties of RDMSH1.

Overlap Algebras: a Constructive Look at Complete Boolean Algebras [PDF]
The notion of a complete Boolean algebra, although completely legitimate in constructive mathematics, fails to capture some natural structures such as the lattice of subsets of a given set.
