Coherent double coverings of virtual link diagrams. (arXiv:1712.09348v1 [math.GT])
来源于:arXiv
A virtual link diagram is called normal if the associated abstract link
diagram is checkerboard colorable, and a virtual link is normal if it has a
normal diagram as a representative. Normal virtual links have some properties
similar to classical links.In this paper, we introduce a method of converting a
virtual link diagram to a normal virtual link diagram. We show that the normal
virtual link diagrams obtained by this method from two equivalent virtual link
diagrams are equivalent. We discuss the relationship between this method and
some invariants of virtual links. 查看全文>>
