It is shown thatsubtractive strong co-ideals are intersection of all primal strong co-ideals that contain them. Also we prove that the representation of strong co-ideals as reduced intersections of primal strong co-ideals is unique. %U https://jart.guilan.ac.ir/article_56_aa49e7fee2d91c7e37a8cc981dd8895e.pdf
