# Pythagorean fuzzy subsets

@article{Yager2013PythagoreanFS, title={Pythagorean fuzzy subsets}, author={R. Yager}, journal={2013 Joint IFSA World Congress and NAFIPS Annual Meeting (IFSA/NAFIPS)}, year={2013}, pages={57-61} }

We introduce a new class of non-standard fuzzy subsets called Pythagorean fuzzy subsets and the related idea of Pythagorean membership grades. We focus on the negation operation and its relationship to the Pythagorean theorem. We compare Pythagorean fuzzy subsets with intuitionistic fuzzy subsets. We look at the basic set operations for the Pythagorean fuzzy subsets.
