On Rough Covexsity Sets

Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2013, Vol 4, Issue 3

Abstract

In this paper, we introduced new concepts for surely and possibly , start shaped (convex ) set. Also for rough start shaped ( rough convex) set .We established the neccessary and sufficient conditions for a set to be star shaped (convex ) set or rough starshaped ( rough convex) set . Finally ,we introduced new concepts for star shaped (convex ) relation.
