Abstract

In this research, we introduce a recent type of open set, called a pre-feebly-open set, obtained by accrediting the feebly open set. We have defined and studied this type and specified several of its characteristics. We found some features and connections with other sets, obtained results that explain them, and symbolized them with the symbol pre-feebly-open. Also, we introduced and defined the notions of pre-f-closure and pre-f-interior. As well as offer the properties, prove them, and others.
