Galois Connections in Categorial Type Logic [PDF]
AbstractThe introduction of unary connectives has proved to be an important addition to the categorial vocabulary. The connectives considered so far are order-preserving; in this paper instead, we consider the addition of order-reversing, Galois connected operators. In §2 we do the basic model-theoretic and proof-theoretic groundwork.

Constructive Galois Connections [PDF]
Abstract Galois connections are a foundational tool for structuring abstraction in semantics, and their use lies at the heart of the theory of abstract interpretation. Yet, mechanization of Galois connections using proof assistants remains limited to restricted modes of use, preventing their general application in

Relational Galois connections between transitive fuzzy digraphs [PDF]
Fuzzy-directed graphs are often chosen as the data structure to model and implement solutions to several problems in the applied sciences. Galois connections have also shown to be useful both in theoretical and in practical problems.

Transport via Partial Galois Connections and Equivalences [PDF]
Multiple types can represent the same concept. For example, lists and trees can both represent sets. Unfortunately, this easily leads to incomplete libraries: some set-operations may only be available on lists, others only on trees.

Galois Connections in Persistent Homology [PDF]
We present a new language for persistent homology in terms of Galois connections. This language has two main advantages over traditional approaches. First, it simplifies and unifies central concepts such as interleavings and matchings.

Representation of Fuzzy Concept Lattices in the Framework of Classical FCA
We describe a representation of the fuzzy concept lattices, defined via antitone Galois connections, within the framework of classical Formal Concept Analysis. As it is shown, all needed information is explicitly contained in a given formal fuzzy context

Some Galois Connections in Elementary Number Theory [PDF]
We study some Galois connections between partially ordered sets of interest in arithmetic: the natural numbers and the integers ordered by magnitude or by ...

Galois theory for iterative connections and nonreduced Galois groups [PDF]
This article presents a theory of modules with iterative connection. This theory is a generalisation of the theory of modules with connection in characteristic zero as given by N. Katz to modules over rings of arbitrary characteristic. We show that these

Some Galois connections arising from Morita contexts of semigroups [PDF]
We show that a unitary surjective Morita context connecting two semigroups yields Galois connections between certain lattices of compatible relations whenever either semigroup has common weak local units.

This paper is an attempt to develop quantitative domain theory over frames. Firstly, we propose the notion of a fuzzy basis, and several equivalent characterizations of fuzzy bases are obtained.
