COMPACTNESS IN PYTHAGOREAN FUZZY TOPOLOGICAL SPACES
Asian Journal of Mathematics and Computer Research, Volume 26, Issue 3,
Page 131-138
Abstract
In this paper, the concept of Pythagorean fuzzy compactness, Pythagorean fuzzy almost compactness and Pythagorean fuzzy near compactness are introduced and studied. We give some characterizations of Pythagorean fuzzy almost compactness in terms of Pythagorean fuzzy regular open or Pythagorean fuzzy regular closed. Also, we investigate the behavior of Pythagorean fuzzy compactness under several types of Pythagorean fuzzy continuous.
Keywords:
- Pythagorean fuzzy subsets
- pythagorean fuzzy topology
- pythagorean fuzzy continuity
- pythagorean fuzzy compactness
