Zero-Set Intersection Graph On C+(X)

For any Tychonoff space X we have introduced the zero-set in-tersection graph on {Γ}(C+(X)) and studied the graph properties in connection with the algebraic properties of the semiring C+(X). We have shown that for any two realcompact spaces X and Y the graph isomorphism between {Γ}(C+(X)) and {Γ}(C+(Y )), the semiring isomorphism between C+(X) and C+(Y ), the topological homeomorphism between X and Y, the ring isomorphism between C(X) and C(Y ) and the graph isomorphism between {Γ}(C(X)) and {Γ}(C(Y )) are equivalent.
