有色Alexander不变量的拓扑模型

A topological model for the coloured Alexander invariants

Cristina Ana-Maria Anghel

摘要:

有色亚历山大多项式形成一个非半单量子不变量序列,该序列来自单位根量子群$U_q(sl(2))$的表示论。该序列恢复原始亚历山大多项式作为首项。我们给出了这个不变量的拓扑模型,表明它们可以得到作为分级交叉配对之间的同源类覆盖的配置空间中的穿孔盘。

英文摘要:

Coloured Alexander polynomials form a sequence of non-semisimple quantum invariants coming from the representation theory of the quantum group $U_q(sl(2))$ at roots of unity. This sequence recovers the original Alexander polynomial as the first term. We give a topological model for this invariants, showing that they can be obtained as graded intersection pairings between homology classes in a covering of the configuration space in the punctured disc.
