Diophantine approximation on rational quadrics
Cornelia Drutu
We compute the Hausdorff dimension of sets of very well approximable vectors on rational quadrics. We use ubiquitous systems and the geometry of locally symmetric spaces. As a bypr…

Relatively Hyperbolic Groups with Rapid Decay Property
Cornelia Drutu, Mark Sapir
We prove that a finitely generated group hyperbolic relative to the collection of finitely generated subgroups H_1,..., H_m has the Rapid Decay property if and only if each H_i…

Non-linear residually finite groups
Cornelia Drutu, Mark Sapir
We give the first example of a non-linear residually finite 1-related group: < a, t | a^{t^2}=a^2>.
