Abstract: The purpose of this paper is to introduce the concepts of s ̃p_c – closure and s ̃p_c – interior operations and study the properties of s ̃p_c – closure and s ̃p_c – interior of a soft set in a soft topological space, also we aim to study properties of s ̃p_c– derived, s ̃p_c– frontier and s ̃p_c– Exterior of soft set using the concept of s ̃p_c– open set. Finally we introduce the concept of almost s ̃p_c– continuous mapping and investigate properties and characterizations of these new types of mapping.
Keywords: Soft Closed Set, Soft Pre–Open Set, s ̃p_c–Open Set And s ̃p_c–Almost Continuity
