Path covering number and L(2,1)-labeling number of graphs
Changhong Lu, Qing Zhou
A {\it path covering} of a graph is a set of vertex disjoint paths of containing all the vertices of . The {\it path covering number} of , denoted by , is the m…
On tame embeddings of solenoids into 3-space
Boju Jiang, Shicheng Wang, Hao Zheng +1
Solenoids are ``inverse limits'' of the circle, and the classical knot theory is the theory of tame embeddings of the circle into the 3-space. We give some general study, including…
Embedding infinite cyclic covers of knot spaces into 3-space
Boju Jiang, Yi Ni, Shicheng Wang +1
We say a knot in the 3-sphere has {\it Property } if the infinite cyclic cover of the knot exterior embeds into . Clearly all fibred knots have P…
Generalized Hopfian property, minimal Haken manifold, and J. Simon's conjecture for 3-manifold groups
Alan W. Reid, Shicheng Wang, Qing Zhou
We address a conjecture that -surjective maps between closed aspherical 3-manifolds having the same rank on must be of non-zero degree. The conjecture is proved for Seif…
On finiteness of the number of boundary slopes of immersed surfaces in 3-manifolds
Joel Hass, Shicheng Wang, Qing Zhou
For any hyperbolic 3-manifold with totally geodesic boundary, there are finitely many boundary slopes for essential immersed surfaces of a given genus. There is a uniform bound…
Any 3-manifold 1-dominates at most finitely many geometric 3-manifolds
Shicheng Wang, Qing Zhou
In this paper, we proved that any closed orientable 3-manifold 1-dominates at most finitely many geometric 3-manifolds.
