Pythagorean fuzzy points and applications in pattern recognition and Pythagorean fuzzy topologies.

In this paper, we define the concept of Pythagorean fuzzy point. We define a similarity measure between Pythagorean fuzzy points, and we give an application of this similarity measure in pattern recognition. We also introduce a new type of continuity for the functions defined between two Pythagorean fuzzy topological spaces. Moreover, we introduce the concept of Moore–Smith convergence in Pythagorean fuzzy topological space, and we investigate the relationship between convergence of nets and continuity.
