A graphical description of the BNS-invariants of Bestvina-Brady groups and the RAAG recognition problem
Yu-Chan Chang, Lorenzo Ruffoni
A finitely presented Bestvina-Brady group (BBG) admits a presentation involving only commutators. We show that if a graph admits a certain type of spanning trees, then the associat…

Manifolds without real projective or flat conformal structures
Lorenzo Ruffoni
In any dimension at least five we construct examples of closed smooth manifolds with the following properties: 1) they have neither real projective nor flat conformal structures; 2…

Special cubulation of strict hyperbolization
Jean-François Lafont, Lorenzo Ruffoni
We prove that the Gromov hyperbolic groups obtained by the strict hyperbolization procedure of Charney and Davis are virtually compact special, hence linear and residually finite.…
