Rectangle condition for compression body and 2-fold branched covering

Jungsoo Kim, Jung Hoon Lee

We give the rectangle condition for strong irreducibility of Heegaard splittings of $3$ -manifolds with non-empty boundary. We apply this to a generalized Heegaard splitting of a $2…

Examples of unstabilized critical Heegaard surfaces

Jung Hoon Lee

We show that the standard minimal genus Heegaard splitting of (closed orientable surface)\times S^1 is a critical Heegaard splitting.

Twisted torus knots T(p,q,3,s) are tunnel number one

Jung Hoon Lee

We show that twisted torus knots $T (p, q, 3, s)$ are tunnel number one. A short spanning arc connecting two adjacent twisted strands is an unknotting tunnel.
