Effective length-projection bounds for hyperbolic 3-manifolds diffeomorphic to $S \times R$

Gabriele Viaggi

We give a formula with explicit constants relating the subsurface projection $d_{Y} (ν^{-}, ν^{+})$ of the end invariants $ν^{-}, ν^{+}$ of a hyperbolic 3-manifold $Q$ diffeomorphic to $S\times…

Effective hyperbolization and length bounds for Heegaard splittings

Peter Feller, Alessandro Sisto, Gabriele Viaggi

We consider 3-manifolds given as Heegaard splittings $M = H^{-} \cup_{Σ} H^{+}$ with the aim to describe the hyperbolic metric of $M$ under topological conditions on the splitting guaranteei…

Geometry of hyperconvex representations of surface groups

James Farre, Beatrice Pozzetti, Gabriele Viaggi

We study the geometry of hyperconvex representations of surface groups in $PSL (d, C)$ and their deformation spaces: We produce a natural holomorphic extension of the…
