Ergodicity of Bowen-margulis Measure for the Benoist 3-manifolds: Extended Version
نویسنده
چکیده
We study the geodesic flow of a class of 3-manifolds introduced by Benoist which have some hyperbolicity but are non-Riemannian, not CAT(0), and with non-C geodesic flow. The geometries are nonstrictly convex Hilbert geometries in dimension three which admit compact quotient manifolds by discrete groups of projective transformations. We prove the Patterson-Sullivan density is canonical, with applications to counting, and construct explicitly the Bowen-Margulis measure of maximal entropy. The main result of this work is ergodicity of the Bowen-Margulis measure. Remark 0.1. This version of the paper has been expanded upon for clarity and readability, and is not for publication.

Flat strips, Bowen-Margulis measures, and mixing of the geodesic flow for rank one CAT(0) spaces
Let X be a proper, geodesically complete CAT(0) space under a proper, non-elementary, isometric action by a group Γ with a rank one element. We construct a generalized Bowen-Margulis measure on the space of unit-speed parametrized geodesics of X modulo the Γ-action. Although the construction of Bowen-Margulis measures for rank one nonpositively curved manifolds and for CAT(−1) spaces is well-kn...
متن کاملBowen{margulis and Patterson Measures on Negatively Curved Compact Manifolds
We give a new simple construction of the maximal entropy invariant measure (the Bowen{Margulis measure) for the geodesic ow on a compact negatively curved manifold. This construction directly connects invariant`conformal density" arising from the Patterson measure on the sphere at innnity of the universal covering space with the maximal entropy measureof the geodesic ow. 0. Introduction Let M b...
متن کاملIntrinsic Ergodicity via Obstruction Entropies
Bowen showed that a continuous expansive map with specification has a unique measure of maximal entropy. We show that the conclusion remains true under weaker non-uniform versions of these hypotheses. To this end, we introduce the notions of obstructions to expansivity and specification, and show that if the entropy of such obstructions is smaller than the topological entropy of the map, then t...
متن کاملAn Extension of Quantitative Nondivergence and Applications to Diophantine Exponents
This paper continues the theme started in 1971 by G.A. Margulis [22] when he showed that trajectories of one-parameter unipotent flows on SL(k,R)/ SL(k,Z) are never divergent. This was earlier conjectured by I. Piatetski-Shapiro, and was used by Margulis for the proof of the Arithmeticity Theorem for non-uniform lattices. A decade later, S. G. Dani [7, 8, 10] modified the method of Margulis, sh...

Let G := SO(n, 1)◦ and Γ < G be a geometrically finite Zariski dense subgroup with critical exponent δ bigger than (n − 1)/2. Under a spectral gap hypothesis on L(Γ\G), which is always satisfied when δ > (n − 1)/2 for n = 2, 3 and when δ > n − 2 for n ≥ 4, we obtain an effective archimedean counting result for a discrete orbit of Γ in a homogeneous space H\G where H is the trivial group, a symm...
