Improved algebraic fibrations of high-dimensional hyperbolic groups
Giovanni Italiano, Matteo Migliorini, Andrew Ng
For every , we construct infinitely many quasi-isometry classes of hyperbolic groups of cohomological dimension that algebraically fibre with finitely presented k…
Virtual fibring of Poincaré-duality groups
Sam P. Fisher, Giovanni Italiano, Dawid Kielak
We show that a RFRS Poincaré-duality group admits a virtual epimorphism to the integers whose kernel is itself a Poincaré-duality group over every field if and only if the $L^2…
Dehn functions of subgroups of products of free groups. Part II: Precise computations
Dario Ascari, Federica Bertolotti, Giovanni Italiano +2
We prove that the Bridson-Dison group has quartic Dehn function, thereby providing the first precise computation of the Dehn function of a subgroup of a direct product of free grou…
Dehn functions of subgroups of products of free groups. Part I: Uniform upper bounds
Dario Ascari, Federica Bertolotti, Giovanni Italiano +2
Subgroups of direct products of finitely many finitely generated free groups form a natural class that plays an important role in geometric group theory. Its members include fundam…
