Title: The BNS invariant of the fundamental group of a surface bundle over a surface.

Abstract: We will discuss some new results on the Bieri-Neumann-Strebel invariant of these groups, showing in particular that (with obvious exceptions) they algebraically fiber. As a corollary, we show that for “most” bundles these groups are not coherent.
