Spherical Neutrosophic Coordinates
To Cengiz Kahraman I read with interest your paper: Present Worth Analysis Using Pythagorean Fuzzy Sets, by Cengiz

Kahraman, Sezi Cevik Onar, Basar Oztaysi, Advances in
Intelligent Systems and Computing book series (AISC, volume 642), 30 August 2017. I think it is possible to extend it from Pythagorean Fuzzy
Sets to Spherical Neutrosophic Sets. See pages 20-21 in my book [ Neutrosophic Perspectives:
Triplets, Duplets, Multisets, Hybrid Operators, Modal Logic,
Hedge Algebras. And Applications. Pons Editions, Bruxelles, 2017; http://fs.unm.edu/NeutrosophicPerspectives.pdf ], about
Spherical Neutrosophic Numbers, where the neutrosophic coordinates T, I, F are in the relationship: T2 + I2 + F2 ≤ 3, therefore T, I, F belong to [0, 3 ].
To Said Broumi There is no paper on Pythagorean neutrosophic sets, because the Pythagorean fuzzy and intuitionistic fuzzy sets [based on one or two components respectively] were extended to Spherical Neutrosophic Sets, where we have 3 neutrosophic components, so we are in 3D (or R3).
See my Neutrosophic Perspectives book: t2 + i2 + f2 ≤ 3,
