Lowen uniformity via fuzzifying uniformity

چکیده
The original definition of a topological space given by Hausdorff used neighborhood systems. Lattice-valued maps appear in this context when you identify a topology with a monoid in the Kleisli category of the filter monad on SET. H?hle’s notion of a lattice-valued topology [2] uses the same idea and it’s inspired in the classical lattice-valued topologies. Ltopological spaces are motivated by a crisp notion of openness of a lattice-valued map, where L is a strictly two-sided commutative quantale. On his part, L-fuzzy topological spaces are structures which are capable to express the degree of openness of a lattice-valued map. These spaces constitute topological subcategories of the category of LM -topological spaces introduced by Kubiak and Šostak [3]. As a particular case we can stand out the so-called fuzzifying topologies considered by Ying (1991) whose elements are mappings T: 2 → I satisfying a multivalued version of the topological axioms (here X is a nonempty set and I is the unit closed interval). The category of fuzzifying topological spaces is isomorphic to the category of fuzzy neighborhood spaces which in turn is a topological subcategory of stratified I-topological spaces.

Completely regular fuzzifying topological spaces
The concept of a fuzzifying topology was given in [1] under the name L-fuzzy topology. Ying studied in [9, 10, 11] the fuzzifying topologies in the case of L = [0,1]. A classical topology is a special case of a fuzzifying topology. In a fuzzifying topology τ on a set X , every subset A of X has a degree τ(A) of belonging to τ, 0 ≤ τ(A) ≤ 1. In [4], we defined the degrees of compactness, of loca...
متن کاملHyperspace of a fuzzy quasi-uniform space
The aim of this paper is to present a fuzzy counterpart method of constructing the Hausdorff quasi-uniformity of a crisp quasi-uniformity. This process, based on previous works due to Morsi cite{Morsi94} and Georgescu cite{Georgescu08}, allows to extend probabilistic and Hutton $[0,1]$-quasi-uniformities on a set $X$ to its power set. In this way, we obtain an endofunctor for each one of the c...
متن کاملWeakly induced modifications of I-fuzzy topologies
Since Chang [2] introduced fuzzy theory into topology, many authors have discussed various aspects of fuzzy topology. It is well known that weakly induced and induced topological spaces play an important role in L-topological spaces (see book [8]). According to their value ranges, L-topological spaces form different categories. Clearly, the investigation on their relationships is certainly impo...
متن کاملThe Semicontinuous Quasi-uniformity of a Frame
The aim of this note is to show how various facts in classical topology connected with semicontinuous functions and the semicontinuous quasi-uniformity have their counterparts in pointfree topology. In particular, we introduce the localic semicontinuous quasi-uniformity, which generalizes the semicontinuous quasiuniformity of a topological space (known to be one of the most important examples o...
متن کاملNon-uniformity of Clinical Head, Head and Neck, and Body Coils in Magnetic Resonance Imaging (MRI)
Introduction Signal intensity uniformity in a magnetic resonance (MR) image indicates how well the MR imaging (MRI) system represents an object. One of the major sources of image non-uniformity in high-field MRI scanners is inhomogeneity of radio-frequency coil. The aim of this study was to investigate non-uniformity in head, head and neck, and body coils and compare the obtained results to det...
