The Volume of complete anti-de Sitter 3-manifolds

Up to a finite cover, closed anti-de Sitter $3$-manifolds are quotients of $\mathrm{SO}_0(2,1)$ by a discrete subgroup of $\mathrm{SO}_0(2,1) \times \mathrm{SO}_0(2,1)$ of the form \[j\times

On deformation spaces of nonuniform hyperbolic lattices

Abstract Let Γ be a nonuniform lattice acting on the real hyperbolic n-space. We show that in dimension greater than or equal to 4, the volume of a representation is constant on each connected

A note on the integrality of volumes of representations

Let Γ be a torsion-free, non-uniform lattice in SO ( 2 n, 1 ) . We present an elementary, combinatorial–geometrical proof of a theorem of Bucher, Burger, and Iozzi in [BBI21] which states that the

We establish sufficient conditions for a cohomology class of a discrete subgroup Γ of a connected semisimple Lie group with finite center to be representable by a bounded differential form on the

A Dual Interpretation of the Gromov–Thurston Proof of Mostow Rigidity and Volume Rigidity for Representations of Hyperbolic Lattices

We use bounded cohomology to define a notion of volume of an \(\operatorname{SO}(n,1)\)-valued representation of a lattice \(\varGamma<\operatorname{SO}(n,1)\) and, using this tool, we give a

Maximal Volume Representations are Fuchsian

AbstractWe prove a volume-rigidity theorem for Fuchsian representations of fundamental groups of hyperbolic k-manifolds into Isom $$\mathbb{H}^n$$. Namely, we show that if M is a complete hyperbolic

Hyperbolic volume of representations of fundamental groups of cusped 3-manifolds

Let W be a compact manifold and let ρ be a representation of its fundamental group into PSL(2, C). Then the volume of ρ is defined by taking any ρ-equivariant map from the universal cover W~ to ℍ 3

A volume invariant is used to characterize those representations of a countable group into a connected semisimple Lie group G which are injective and whose image is a discrete cocompact subgroup of

The norm of the Euler class

We prove that the norm of the Euler class $${\mathcal {E}}$$ for flat vector bundles is 2−n (in even dimension n, since it vanishes in odd dimension). This shows that the Sullivan–Smillie bound
