Virtual domination of 3-manifolds II
Hongbin Sun
For any closed oriented 3-manifold with positive simplicial volume and any closed oriented 3-manifold , we prove that there exists a finite cover of that admits a d…
On the degree of a finite cover which fibers over circle
Inkang Kim, Hongbin Sun
We give a lower bound for the degree of a finite cover of a hyperbolic 3-manifold which fibers over the circle, in terms of volume, the diameter of the manifold and other new invar…
Maps from 3-manifolds to 4-manifolds that induce isomorphisms on
Hongbin Sun, Zhongzi Wang
In this paper, we prove that any closed orientable 3-manifold other than and satisfies the following properties: (1) For any compact orientable 4-man…
Minimal Euler Characteristics of 4-manifolds with 3-manifold groups
Hongbin Sun, Zhongzi Wang
Let for a compact 3-manifold , and let , and be the invariants of Hausmann-Weinberger, Kotschick and Hillman respectively. For certain class of compact…
All finitely generated 3-manifold groups are Grothendieck rigid
Hongbin Sun
In this paper, we prove that all finitely generated 3-manifold groups are Grothendieck rigid. More precisely, for any finitely generated 3-manifold group and any finitely gener…
