rigidity of codimension one higher rank actions
abstract:
we discuss work in progress regarding the following assertion: let $g$ be a simple higher rank lie group, then any closed manifold $m$, admitting a smooth locally free action of $g$, with codimension one orbits, is finitely and equivariantly covered by $g/\gamma \times s^1$, for some cocompact lattice $\gamma$ of $g$, where $g$ acts by left translations on the first factor, and trivially on $s^1$. this result is in the spirit of the zimmer program. we will focus on the case $g = \mathrm{sl}(3,\mathbb{r})$ for the talk.
