closed essential surface in M with g.F / 1 which cuts M into M1 and M2. In the present paper, we show the following theorem: Suppose that there is no essential surface with boundary.Qi; @Qi / in.Mi;F / satisfying .Qi/>2Cg.F /2g.Mi /, i D 1; 2. Then g.M /Dg.M1/Cg.M2/g.F /. As a consequence, we further show that if Mi has a Heegaard splitting Vi[SiWi with distance D.Si/2g.Mi/g.F /, i D 1; 2, then g.M /D g.M1/Cg.M2/g.F /. The main results follow from a new technique which is a stronger version of Schultens’ Lemma. 57M99, 57N10; 57M2
