循环不变量与有向奇异纽结

Cocycle Invariants and Oriented Singular Knots

Jose Ceniceros, Indu R. Churchill, Mohamed Elhamdadi, Mustafa Hajij

摘要:

我们扩展quandle上循环不变的定向奇异结和链接使用代数结构称为\emph{oriented singquandles}和分配权函数在经常和奇异的交叉。这个不变量与经典结的经典上循环不变量相吻合,但提供了关于奇异结和链接的额外信息。新的不变量区分奇异的奶奶结和奇异的方形结。

英文摘要:

We extend the quandle cocycle invariant to oriented singular knots and links using algebraic structures called \emph{oriented singquandles} and assigning weight functions at both regular and singular crossings. This invariant coincides with the classical cocycle invariant for classical knots but provides extra information about singular knots and links. The new invariant distinguishes the singular granny knot from the singular square knot.
