焊接杆件Milnor不变量的组合方法

Combinatorial approach to Milnor invariants of welded links

Haruko A. Miyazawa, Kodai Wada, Akira Yasuhara

摘要:

对于一个经典的链接,米尔诺尔定义了一个家庭的同痕不变量,称为米尔诺尔$\overlineμ$ -不变量。最近,Chrisman通过拓扑方法将Milnor $\overlineμ$ -不变量推广到焊接连接。本文的目的是表明,米尔诺尔$\overlineμ$ -不变量可以扩展到焊接环节的组合方法。证明包含一个替代证明的不变性的原始$\overlineμ$ -不变量的经典链接。

英文摘要:

For a classical link, Milnor defined a family of isotopy invariants, called Milnor $\overlineμ$-invariants. Recently, Chrisman extended Milnor $\overlineμ$-invariants to welded links by a topological approach. The aim of this paper is to show that Milnor $\overlineμ$-invariants can be extended to welded links by a combinatorial approach. The proof contains an alternative proof for the invariance of the original $\overlineμ$-invariants of classical links.
