Abstract

Through this paper, we will discuss the limit points of a set and its complement set. To do this the authors will consider Acherjee et al.’s mathematical structure primal. These limit points via primal will further express the representation of nowhere dense sets in the literature. Expression of ⋄-local function and its associated set-valued set function will also be discussed here. Levine’s semi-open sets will also be further represented by these limit points and will be decomposed.

Keywords
