Self-mapping degrees of torus bundles and torus semi-bundles

Hongbin Sun, Shicheng Wang, Jianchun Wu

Each closed oriented 3-manifold $M$ is naturally associated with a set of integers $D (M)$ , the degrees of all self-maps on $M$ . $D (M)$ is determined for each torus bundle and torus…

Additivity of Heegaard genera of bounded surface sums

Ruifeng Qiu, Shicheng Wang, Mingxing Zhang

Let $M$ be a surface sum of 3-manifolds $M_{1}$ and $M_{2}$ along a bounded connected surface $F$ and $\partial_{i}$ be the component of $\partial M_{i}$ containing $F$ . If $M_{i}$ has a hig…

On standard forms of 1--dominations between knots with same Gromov volumes

Michel Boileau, Yi Ni, Shicheng Wang

Let $k$ and $k^{'}$ be two knots in 3-sphere. Say $k$ 1--dominates $k^{'}$ , if there is a proper degree 1 map $f\co E(k)\to E(k')$, between knot exterior of $k_{i}$ . Theorem: Suppose that…

Finiteness of mapping degrees and $PSL (2, R)$ -volume on graph manifolds

Pierre Derbez, Shicheng Wang

For given closed orientable 3-manifolds $M$ and $N$ let $cD (M, N)$ be the set of mapping degrees from $M$ to $N$ . We address the problem: For which $N$ , $cD (M, N)$ is finite for all…
