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 $π_{1}$ -surjective maps between closed aspherical 3-manifolds having the same rank on $π_{1}$ 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 $M$ 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.
