Dodecahedral L-spaces and hyperbolic 4-manifolds
Ludovico Battista, Leonardo Ferrari, Diego Santoro
We prove that exactly 6 out of the 29 rational homology 3-spheres tessellated by four or less right-angled hyperbolic dodecahedra are L-spaces. The algorithm used is based on the L…

Cusps of hyperbolic 4-manifolds and rational homology spheres
Leonardo Ferrari, Alexander Kolpakov, Leone Slavich
In the present paper, we construct a cusped hyperbolic -manifold with all cusp sections homeomorphic to the Hantzsche-Wendt manifold, which is a rational homology sphere. By a r…
