Topological Structure of Complex

Abstract

The novel concept of topological spaces in complex Pythagorean fuzzy environment is addressed in this paper. Also we introduced the notions of interior and closure operators of a complex Pythagorean fuzzy topological spaces and the properties of these operators are verified as a justification of these operators. The definitions of a complex Pythagorean fuzzy subspace and bases for the topology are given. Also a continuous mappings on complex Pythagorean fuzzy sets are deliberated. A multiple attribute decision making (MADM) algorithm using complex Pythagorean fuzzy topological spaces is defined and investigated with a numerical example as an application for the provided topological spaces.
