Cut pairs and Morse splitting of finitely generated groups
Suzhen Han, Hao Liang, Qing Liu
Bowditch's theorem for hyperbolic groups establishes a fundamental correspondence between splittings over two-ended subgroups and the existence of local cut points in the Gromov bo…
On Topology of Three-dimensional Continua with Singular Points
Hao Liang, Yunhao Qiu, Yan Tan +1
We propose to model the topology of three-dimensional (3D) continua by Yin sets, regular open semianalytic sets with bounded boundary. Our model differs from manifold-based models…
Boundary rigidity of Gromov hyperbolic spaces
Hao Liang, Qingshan Zhou
We introduce the concept of boundary rigidity for Gromov hyperbolic spaces. We show that a proper geodesic Gromov hyperbolic space with a pole is boundary rigid if and only if its…
Homomorphisms to 3-manifold groups
Daniel Groves, Michael Hull, Hao Liang
We prove foundational results about the set of homomorphisms from a finitely generated group to the collection of all fundamental groups of compact 3-manifolds and answer questions…
