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. This provides some further evidence for the veracity of the Auslander Conjecture. Along the way, we provide a simple cohomological criterion for aspherical manifolds with normal amenable subgroups of $\pi_1$ to have vanishing simplicial volume. This answers a special case of a question due to L\"uck. 
Closed complete affine manifolds cannot have Anosov holonomy.
The conjecture of Auslander is that a closed complete affine manifold must have a virtually solvable fundamental group. We present some supporting evidence. We will show that a closed manifold with a
Closed complete special affine manifolds cannot have Anosov holonomy
The conjecture of Auslander is that a closed complete affine manifold must have a virtually solvable fundamental group. We present some supporting evidence. We will show that a closed manifold with a
Positivity of simplicial volume for nonpositively curved manifolds with a Ricci-type curvature condition
We show that closed manifolds supporting a nonpositively curved metric with negative $([\frac{n}{4}]+1)$-Ricci curvature, have positive simplicial volume. This answers a special case of a conjecture
The spectrum of simplicial volume
New constructions in group homology allow us to manufacture high-dimensional manifolds with controlled simplicial volume. We prove that for every dimension bigger than 3 the set of simplicial volumes
On the simplicial volume and the Euler characteristic of (aspherical) manifolds
. A well-known question by Gromov asks whether the vanishing of the simplicial volume of oriented closed aspherical manifolds implies the vanishing of the Euler characteristic. We study various
Complete affine manifolds with Anosov holonomy groups II: partially hyperbolic holonomy and cohomological dimensions
Let N be a complete affine manifold An/Γ of dimension n where Γ is an affine transformation group and K(Γ, 1) is realized as a finite CWcomplex. N has a partially hyperbolic holonomy group if the
Gromov's theory of multicomplexes with applications to bounded cohomology and simplicial volume
The simplicial volume is a homotopy invariant of manifolds introduced by Gromov in 1982. In order to study its main properties, Gromov himself initiated the dual theory of bounded cohomology, that
