Closure and Interior Operators of the Category of Positive Topologies
Joaquín Luna-Torres
We define and study the notions of closure $\text{\rsfs{C}}$ operators and interior operators of the category of convergent covers which appears in pos…
Interor and h operators on the category of locales
JoaquÍn Luna-Torres
We present the concept of interior operator on the category of locales and then we construct a topological category \linebreak $\big(\mathbf{I\text{-}Loc},\ U\bi…
Filters and G-convergence in Categories
Joaquin Luna-Torres
In analogy with the classical theory of filters, for finitely complete categories, we provide the concepts of filter, G-neighborhood (short for \Grothendieck-neighborhood") and cov…
Grothendieck-topological Group Objects
Joaquin Luna-Torres
In analogy with the classical theory of topological groups, for finitely complete categories enriched with Grothendieck topologies, we provide the concepts of localized G-topologic…
Sheaves in Elementary Mathematics: The case of positive integer numbers
Joaquin Luna-Torres
We aim to use the concept of sheaf to establish a link between certain aspects of the set of positive integers numbers, a topic corresponding to the elementary mathematics, and som…
Fixed and variable-basis fuzzy closure operators
Joaquin Luna-Torres
Closure operators are very useful tools in several areas of classical mathematics and in general category theory. In fuzzy set theory, fuzzy closure operators have been studied by…
