F^2 x R中的全局纽结理论

Global knot theory in F^2 x R

Thomas Fiedler

摘要:

我们在F^2 × R中引入了一类特殊的结点,称为全局结点,并为全局结点构造了新的同痕不变量,称为T-不变量。一些T-不变量是有限型的,但它们不能从广义Kontsevitch积分中提取出来(因此对于有限类的整体节点来说,广义Kontsevitch积分不是有限型的通用不变量)。我们证明了T-不变量分离的某种类型的所有全球结。作为推论,我们证明了S^3中某些链环的不可逆性,而不使用任何链环群。

英文摘要:

We introduce a special class of knots, called global knots, in F^2 x R and we construct new isotopy invariants, called T-invariants, for global knots. Some T-invariants are of finite type but they cannot be extracted from the generalized Kontsevitch integral (which is consequently not the universal invariant of finite type for the restricted class of global knots). We prove that T-invariants separate all global knots of a certain type. As a corollary, we prove the non-invertibility of some links in S^3 without making any use of the link group.
