Abstract: |
Let $M$ be a compact orientable irreducible 3-manifold, and $F$ be
an essential connected closed surface in $M$ which cuts $M$ into
two manifolds $M_{1}$ and $M_{2}$. If $M_{i}$ has a minimal
Heegaard splitting $M_{i}=V_{i}\cup_{H_{i}}W_{i}$ with $d(H_{1})+d(H_{2})\geq
2(g(M_{1})+g(M_{2})-g(F))+1$, then $g(M)=g(M_{1})+g(M_{2})-g(F)$. |
