Vanishing simplicial volume for certain affine manifolds
Michelle Bucher, Chris Connell, Jean-François Lafont
We show that closed aspherical manifolds supporting an affine structure, whose holonomy map is injective and contains a pure translation, must have vanishing simplicial volume. Thi…

The bounded cohomology of SL_2 over local fields and S-integers
Michelle Bucher, Nicolas Monod
It is proved that the continuous bounded cohomology of SL_2(k) vanishes in all positive degrees whenever k is a non-Archimedean local field. This holds more generally for boundary-…

Surface bundles over surfaces: new inequalities between signature, simplicial volume and Euler characteristic
Michelle Bucher, Caterina Campagnolo
We present three new inequalities tying the signature, the simplicial volume and the Euler characteristic of surface bundles over surfaces. Two of them are true for any surface bun…
