    (2013-03-26) Yusman, Rizan Febri; Gemawati, Sri; Sirait, Asli
    Interval set is a set from an object whose elements consist of intervals. A set of all one-to-one and onto mappings from interval set to the other for all with composition operation which from a semigrup is called interval semigroup. In this paper some symmetric semigroup on certain intervals were discused. Some of the properties discused were isomorphic, S-interval symmetric semigroup, S-weakly cyclic interval symmetric semigroup and S-weakly commutative interval symmetric semigroup which are expressed in some theorems
