This proves that in TS, </em><em>the delta</em><em>-closure of a set is smaller than its delta(delta g)star</em><em>- closure while the delta</em><em>-interior is generally larger than its delta(delta g)star</em><em>- interior. In addition, in the same space the</em> delta(delta g)star-<em>continuous functions, absolute-delta(delta g)star</em><em>- continuous functions and rs -delta(delta g)star</em> <em>- continuous functions are introduced and investigated. Characterization and properties of these functions are also determined. </em></p> <p><em>&nbsp;</em></p> Meriam Niepes Bitasolo Copyright (c) 2019 International Journal For Research In Mathematics And Statistics (ISSN: 2208-2662) 2019-04-19 2019-04-19 5 4 01 08
