Pythagorean m-polar Fuzzy Neutrosophic Metric Spaces

Abstract

Neutrosophy deals with the study of neutrosophic logic, set and probability. A Pythagorean mpolar neutrosophic set is indeed an expansion of crisp, fuzzy, intuitionistic fuzzy, neutrosophic and Pythagorean
m-polar fuzzy sets. In this paper, we develop the perception of Pythagorean m-polar fuzzy neutrosophic metric
space defined over Pythagorean m-polar fuzzy neutrosophic set relying on the classical definition of metric
spaces defined on a crisp set. We present some related results and illustrations to perceive the conceptions.
We present many examples of metrics which hold true for classical sets but fail to make sense in Pythagorean
m-polar fuzzy environment. We also render a practical utility of the proposed metrics in pattern recognition.
