Almost normal Heegaard splittings
Abstract: I will discuss my work in progress on the objects of the
title, which grew out of my efforts to understand Hempel's notion of
the {\em distance} of a splitting. An unexpected application is a new
algorithm to decide if a closed, irreducible, and atoroidal three-manifold
is a surface bundle over the circle.
