Dehn填充后成为同位素的表面

Surfaces that become isotopic after Dehn filling

David Bachman, Ryan Derby-Talbot, Eric Sedgwick

摘要:

我们表明,通用的填充后,沿环面边界组件的3流形,没有两个封闭的,2侧,本质表面成为同位素,没有封闭的,2侧,本质表面成为非本质的。也就是说,本质表面的集合(考虑到合线)在所有适当的通用Dehn填充中保持不变。此外,对于所有,但许多非通用的填充,我们表明,两个基本的表面只能成为同位素的约束方式。

英文摘要:

We show that after generic filling along a torus boundary component of a 3-manifold, no two closed, 2-sided, essential surfaces become isotopic, and no closed, 2-sided, essential surface becomes inessential. That is, the set of essential surfaces (considered up to isotopy) survives unchanged in all suitably generic Dehn fillings. Furthermore, for all but finitely many non-generic fillings, we show that two essential surfaces can only become isotopic in a constrained way.
