On certain permutation groups and sums of two squares
Pietro Corvaja, Carlo Petronio, Umberto Zannier
We consider the question of existence of ramified covers over P_1 matching certain prescribed ramification conditions. This problem has already been faced in a number of papers, bu…
Hyperbolic graphs of small complexity
Damian Heard, Craig Hodgson, Bruno Martelli +1
In this paper we enumerate and classify the ``simplest'' pairs (M,G) where M is a closed orientable 3-manifold and G is a trivalent graph embedded in M. To enumerate the pairs we u…
On colored Turaev-Viro invariants for links in arbitrary 3-manifolds
Ekaterina Pervova, Carlo Petronio
We consider certain invariants of links in 3-manifolds, obtained by a specialization of the Turaev-Viro invariants of 3-manifolds, that we call colored Turaev-Viro invariants. Thei…
