环面丛与环面半丛的自映射度

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

Hongbin Sun, Shicheng Wang, Jianchun Wu

摘要:

每个闭定向三维流形$M$自然地与一组整数$D(M)$相关联,整数是$M$上所有自映射的度数。针对每个环面丛和环面半丛$M$确定$D(M)$。详细研究了环面半丛的结构。本文是一个项目的一部分,以确定$D(M)$的所有3-流形瑟斯顿的图片。

英文摘要:

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 semi-bundle $M$. The structure of torus semi-bundle is studied in detail. The paper is a part of a project to determine $D(M)$ for all 3-manifolds in Thurston's picture.
