In this thesis we introduce a new types of semi-open sets called Sp-open sets which is semi-open set and it is a union of preclosed sets. By this set we define a new type of continuity called Sp-continuity and also almost and weakly Sp-continuity are defined. At final we introduce new concept of semi-compactness called Sp-compact spaces.
