New Results On Pythagorean Neutrosophic Open Sets inPythagorean Neutrosophic Topological Spaces

Abstract

In this paper, we analyze the basic algebraic operations of neutrosophic crisp sets and
their properties, show that some operations of neutrosophic crisp sets with type 2 and type 3 are
not closed by counter examples, and give some new operations. Then, discuss some morphological
operators in neutrosophic crisp mathematical morphology, and study the application to edge
extraction of color images, and give some Python programs and related experimental results.
