Picture fuzzy topological spaces and associated continuous functions

Abstract

<abstract> <p>This paper describes a study of picture fuzzy topological spaces. We prove some basic results related to picture fuzzy sets together with the introduction of new notions such as the rank, picture fuzzy base and picture fuzzy sub-base of picture fuzzy topological spaces. With the help of these notions, we present a method to design picture fuzzy topological spaces. Furthermore, we introduce the concept of continuity to picture fuzzy topological spaces and find a necessary and sufficient condition for a picture fuzzy continuous function between two picture fuzzy topological spaces.</p> </abstract>

Bipolar Fuzzy Supra Topology via (Q-) Neighborhood and Its Application in Data Mining Process

“…Topological structures of some extensions of fuzzy sets also have been studied. For example intuitonistic fuzzy topology [24], neutrosophic fuzzy topology [25,26], picture fuzzy topology [27], bipolar fuzzy topology [28], etc.…”

Relation Amidst Fuzzy Hyperlattice-Ordered Group and Hyperlattice Ordered Group

“…Fuzzy set theory is crucial for establishing relations in 0, 1, and multiple domains within hyperstructure theory. This has led to broader research for algebraic hyperstructures and fuzzy-set combinations [10,11]. Many scientists investigated the perception of associating a fuzzy set with a hyperstructure [12][13][14].…”

q‐Rung Orthopair Picture Fuzzy Topological Spaces and Parameter‐Dependent Continuity: Control System Applications

“…Türkarslan et al [28] introduced the topology of q-rung orthopair fuzzy sets. Razaq et al [29] investigated the picture fuzzy topologies and the continuity between these spaces. Furthermore, Öztürk et al [30] conducted an investigation on neutrosophic soft compact spaces.…”
