t-closure Operators

International Journal of General Systems, 2018
In this study, based on the knowledge of the existence of t-norms on an arbitrary given bounded lattice, we introduce t-closure operators with the help of a t-norm on the lattice and a subset of th...

On implicative closure operators in approximate reasoning

International Journal of Approximate Reasoning, 2003
This paper introduces a new class of fuzzy closure operators called implicative closure operators, which generalize some notions of fuzzy closure operators already introduced by different authors.

Distinguishability Operations and Closures

Fundamenta Informaticae, 2016
Given a language L, we study the language of words D(L), that distinguish between pairs of different left quotients of L. We characterize this distinguishability operation, show that its iteration has always a fixed point, and we generalize this result to operations derived from closure operators and Boolean operators. For the case of regular languages,

Closure operations in phylogenetics

Mathematical Biosciences, 2007
Closure operations are a useful device in both the theory and practice of tree reconstruction in biology and other areas of classification. These operations take a collection of trees (rooted or unrooted) that classify overlapping sets of objects at their leaves, and infer further tree-like relationships. In this paper we investigate closure operations

Closure operators constructed by logical operations on bounded lattices

Fuzzy Sets and Systems
In this paper, closure operators obtained from functions having some properties on bounded lattices are defined. By this way, it is aimed to generalize the notions T and U-closure operators obtained from t-norms and uninorms, respectively.
