3-orbifolds的Turaev挠不变量

Turaev Torsion Invariants of 3-orbifolds

Biji Wong

摘要:

我们构造了一个带奇异集的3-orbifolds的组合不变量,它推广了3-流形的Turaev挠不变量。我们给出了几个胶合公式,从中我们得出两个结果。第一个是理解当我们从奇异集中删除一条曲线时,不变量的分量如何变化。第二个是一个公式有关的不变量的3-orbifold的Turaev扭转不变量的基础3-流形的情况下,当奇异集是一个nullhomologous结。

英文摘要:

We construct a combinatorial invariant of 3-orbifolds with singular set a link that generalizes the Turaev torsion invariant of 3-manifolds. We give several gluing formulas from which we derive two consequences. The first is an understanding of how the components of the invariant change when we remove a curve from the singular set. The second is a formula relating the invariant of the 3-orbifold to the Turaev torsion invariant of the underlying 3-manifold in the case when the singular set is a nullhomologous knot.
