扩展的quandle空间和经典链的影子同伦不变量

Extended quandle spaces and shadow homotopy invariants of classical links

Seung Yeop Yang

摘要:

1993年,Fenn、Rourke和Sanderson引入了rack空间和rack同伦不变量,2011年,Noelon引入了quandle空间和quandle同伦不变量的修正。在本文中,我们定义了Cayley型图和扩展的quandle空间的quandle类似的机架和quandle空间。此外,我们还构造了经典链路的影子同伦不变量,并证明了影子同伦不变量等于quandle同伦不变量乘以quandle的阶。

英文摘要:

In 1993, Fenn, Rourke and Sanderson introduced rack spaces and rack homotopy invariants, and modifications to quandle spaces and quandle homotopy invariants were introduced by Nosaka in 2011. In this paper, we define the Cayley-type graph and the extended quandle space of a quandle in analogy to rack and quandle spaces. Moreover, we construct the shadow homotopy invariant of a classical link and prove that the shadow homotopy invariant is equal to the quandle homotopy invariant multiplied by the order of a quandle.
