Orbital counting for relatively Anosov groups

Richard Canary, Tengren Zhang, Feng Zhu +1

We obtain orbital counting results for relatively Anosov groups with respect to linear functionals with finite critical exponent. Our counting results follow from an equidistributi…

A rigidity theorem for complex Kleinian groups

Richard Canary, Tengren Zhang, Andrew Zimmer

Farre, Pozzetti and Viaggi proved that any (d-k)-hyperconvex subgroup of PSL(d,C) is virtually isomorphic to a convex cocompact Kleinian group and that its k-th simple root critica…

Geometry and Dynamics of Transverse Groups

Richard Canary, Tengren Zhang, Andrew Zimmer

We survey recent work on the geometry and dynamics of transverse subgroups of semi-simple Lie groups.

Bi-Lipschitz rigidity of discrete subgroups

Richard Canary, Hee Oh, Andrew Zimmer

We obtain a bi-Lipschitz rigidity theorem for a Zariski dense discrete subgroup of a connected simple real algebraic group. As an application, we show that any Zariski dense discre…

Counting, mixing and equidistribution for GPS systems with applications to relatively Anosov groups

Pierre-Louis Blayac, Richard Canary, Feng Zhu +1

We establish counting, mixing and equidistribution results for finite BMS measures on flow spaces associated to geometrically finite convergence group actions. We show that, in par…

Patterson-Sullivan theory for coarse cocycles

Pierre-Louis Blayac, Richard Canary, Feng Zhu +1

In this paper we develop a theory of Patterson--Sullivan measures associated to coarse cocycles of convergence groups. This framework includes Patterson-Sullivan measures associate…
