摘要：Suppose V ?W-S is a strongly irreducible Heegaard splitting of a compact connected orientable 3-manifold M and F-1 and F-2 are pairwise disjoint homeomorphic essential subsurfaces in partial differential _V. In this paper, we give a suffcient condition such that the self-amalgamation of V ?W-S along F-1 and F-2 is unstabilized and uncritical.
