摘要
在纽结理论中,符号平图与链环投影图之间有着一一对应关系,图的对应的链环投影图的分支数与符号平图的符号无关,确定平图的对应的链环投影图的分支数是用平图研究链环的基本问题之一.给出并证明8.8.6格图和Aztec dia-mond图对应的链环分支数.
In knot theory,there is a one-to-one correspondence between signed plane graphs and link diagrams via the medial construction.The component number of the corresponding link diagram is independent of the signs of the plane graph.Determining the component number of the corresponding link diagram may be one of the basic problems in studying links by using graphs.The paper gives and proves the component number of the corresponding link diagram about the 8.8.6-lattice graphs and the Aztec diamond-graphs.
