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…

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…
