Weaving Geodesics and New Phenomena in Horocyclic Dynamics

Françoise Dal'bo, James Farre, Or Landesberg +1

We construct geometrically infinite hyperbolic surfaces supporting horocycles with tailored recurrence properties. In particular, we obtain the first examples of non-trivial minima…

Classification of horocycle orbit closures in $Z$ -covers

James Farre, Or Landesberg, Yair Minsky

We fully describe all horocycle orbit closures in $Z$ -covers of compact hyperbolic surfaces. Our results rely on a careful analysis of the efficiency of all distance min…

Minimizing laminations in regular covers, horospherical orbit closures, and circle-valued Lipschitz maps

James Farre, Or Landesberg, Yair Minsky

We expose a connection between distance minimizing laminations and horospherical orbit closures in $Z$ -covers of compact hyperbolic manifolds. For surfaces, we provide nov…

Horospherically invariant measures and finitely generated Kleinian groups

Or Landesberg

Let $Γ < P S L_{2} (C)$ be a Zariski dense finitely generated Kleinian group. We show all Radon measures on $P S L_{2} (C) /Γ$ which are ergodic and invariant under the…

On Radon measures invariant under horospherical flows on geometrically infinite quotients

Or Landesberg, Elon Lindenstrauss

We consider a locally finite (Radon) measure on $S O^{+} (d, 1) /Γ$ invariant under a horospherical subgroup of $S O^{+} (d, 1)$ where $Γ$ is a discrete, but not necessarily geometricall…
