Abstract:

We consider a Heegaard splitting $M=H_1\cup _S H_2$ of a $3$-manifold $M$ having an essential disk $D$ in $H_1$ and an essential surface $F$ in $H_2$ with $|D\cap F|=1$.

From $H_1\cup _S H_2$, we obtain another Heegaard splitting $H’_1\cup _{S’} H’_2$ by removing a neighborhood of $F$ from $H_2$ and attaching it to $H_1$. As an application, by using a theorem due to Casson and Gordon, we give examples of $3$-manifolds admitting two Heegaard splittings of distinct genera, where one of them is a strongly irreducible non-minimal genus splitting and it is obtained from the other by the above construction.

We also show that all Heegaard splittings of a Seifert fibered space are related via the above construction.
