Mapping class groups of Heegaard splittings of surface bundles

Jesse Johnson

Published 2012-01-12, updated 2012-04-06Version 3

Every surface bundle with genus $g$ fiber has a canonical Heegaard splitting of genus $2g+1$. We classify the mapping class groups of such Heegaard splittings in the case when the surface bundle has a sufficiently complicated monodromy map.
