Mapping class groups of Heegaard splittings of surface bundles

Geometric Topology 2012-04-09 v3

Abstract

Every surface bundle with genus gg fiber has a canonical Heegaard splitting of genus 2g+12g+1. We classify the mapping class groups of such Heegaard splittings in the case when the surface bundle has a sufficiently complicated monodromy map.
