Mapping class groups of once-stabilized Heegaard splittings

Jesse Johnson

Published 2011-08-26, updated 2013-04-26Version 3

We show that if a Heegaard splitting is the result of stabilizing a high distance Heegaard splitting exactly once then its mapping class group is finitely generated.

Comments: 13 pages. 8 figures. The latest version contains new figures and improvements to the exposition
