We present a new Galois connection that allows building a concept lattice that can be considered to work with the notion of granularity. 2. Preliminaries. 2.1.

This paper establishes an ordering between partial formal contexts, which are trivalued contexts. We use three values to represent the presence or absence ...

Aug 7, 2024 · Galois connections link two ordered sets through paired functions, forming a powerful tool in lattice theory. They generalize to categories as adjoint functors.

In mathematics, especially in order theory, a Galois connection is a particular correspondence (typically) between two partially ordered sets (posets).

A graded partial formal context is a triple ℙ = (𝐺,𝑀,𝐼) where 𝐺 and 𝑀 are sets whose elements are called objects and attributes respectively, and 𝐼 is an ℂ-set ...

Jul 1, 2024 · We present extended theoretical results on heterogeneous formal contexts, including bimorphisms, Galois connections, and heterogeneous attribute implications.
