Weak rank rigidity for groups with a navigable path system

Cornelia Drutu, Davide Spriano, Stefanie Zbinden

We show that groups with a mild form of non-positive curvature (a navigable path system) satisfy the weak rank rigidity conjecture: they either have linear divergence or a Morse el…

Weak Morse properties in spaces with bounded combings

Cornelia Drutu, Davide Spriano, Stefanie Zbinden

We relate two notions of non-positive curvature: bounded combings and the Morse local-to-global (MLTG) property (in its weak and strong version). The latter is a property of a spac…

Actions of acylindrically hyperbolic groups on

Cornelia Drutu, John M. Mackay

We construct affine uniformly Lipschitz actions on and for certain groups with hyperbolic features. For acylindrically hyperbolic groups, our actions have unbounded…

Effective equidistribution of expanding horospheres in the locally symmetric space SO(d) \ SL(d,R) / SL(d,Z)

Cornelia Druţu, Norbert Peyerimhoff

We use a dictionary between lattice point counting inside dilated d-dimensional ellipsoids (Euclidean counting) and counting of lifts of a closed horosphere that intersect a ball o…

Median geometry for spaces with measured walls and for groups

Indira Chatterji, Cornelia Druţu

We show that uniform lattices of isometries of products of real hyperbolic spaces act properly discontinuously and cocompactly on a median space. For lattices in products of at lea…

Random groups, random graphs and eigenvalues of p-Laplacians

Cornelia Drutu, John M. Mackay

We prove that a random group in the triangular density model has, for density larger than 1/3, fixed point properties for actions on -spaces (affine isometric, and more genera…
