Seifert流形中纽结的BPS不变量
BPS Invariants for a Knot in Seifert Manifolds
摘要:
当规范群为$SU(N)$时,计算了Seifert流形中纽结的同调块.通过对Chern-Simons能级的解析延拓,从威尔逊圈算符的期望值出发,得到了具有规范群表示的同调块。我们还得到了Seifert整同调球面上纽结的解析连续水平和表示的同调块。
英文摘要:
We calculate homological blocks for a knot in Seifert manifolds when the gauge group is $SU(N)$. We obtain the homological blocks with a given representation of the gauge group from the expectation value of the Wilson loop operator by analytically continuing the Chern-Simons level. We also obtain homological blocks with the analytically continued level and representation for a knot in the Seifert integer homology spheres.
