A-多项式与Holonomy扰动
The A-polynomial And Holonomy Perturbations
摘要:
Dunfield-Garoufaldmann和Boyer-Zhang证明了$S^{3}$中非平凡纽结的A-多项式是非平凡的。在本文中,我们利用完整扰动证明了不可约3-流形中非平凡零同伦纽结的A-多项式的非平凡性。同时,我们给出了3-球面中纽结的A-多项式的一个强约束。
英文摘要:
Dunfield-Garoufalidis and Boyer-Zhang proved that the A-polynomial of a nontrivial knot in $S^{3}$ is nontrivial. In this paper, we use holonomy perturbations to prove the non-triviality of the A-polynomial for a nontrivial, null-homotopic knot in an irreducible 3-manifold. Also, we give a strong constraint on the A-polynomial of a knot in the 3-sphere.
