A decomposition of open sets through operator interior. (English) Zbl 1469.54004

Summary: The main idea of this article is to define an operator interior and then to establish a new classes of open sets which will be denoted by \(\psi\). Besides, it shows some of their properties and proves some relations between other types of sets.
