Parity criterion and Dehn twists for unstabilized Heegaard splittings

Jung Hoon Lee

Published 2009-03-03Version 1

We give a parity condition of a Heegaard diagram to show that it is unstabilized. This improves the result of [5]. As an application, we construct unstabilized Heegaard splittings by Dehn twists on any given Heegaard splitting.
