In the theory of Kleinian groups, Sullivan’s classical theorem establishes the correspondence between Patterson-Sullivan measures and Hausdorff measures on the limit sets for convex cocompact Kleinian groups. This connection provides a geometric understanding of Patterson-Sullivan measures, emphasizing their association with the internal metric on limit sets. Recent advancements in the theory of infinite co-volume discrete subgroups of higher-rank Lie groups have brought Anosov subgroups into focus as a natural higher-rank extension of convex cocompact Kleinian groups. This raises an intriguing question: under what conditions do Patterson-Sullivan measures for Anosov subgroups emerge as Hausdorff measures on limit sets with appropriate metrics? In this talk, we disuss joint work with Dongryul Kim and Hee Oh, which provides a definitive answer to this question. We will also discuss several applications, including the analyticity of (p,q)-Hausdorff dimensions as functions on the Teichmuller spaces and spectral properties of the associated locally symmetric manifolds.
