Yoshikawa第八步移动的独立性和带移动的最小生成集
Independence of Yoshikawa eighth move and a minimal generating set of band moves
摘要:
Yoshikawa移动至少在四分之一个世纪前被引入,并且仍然被研究人员积极使用。对于任何有标记的图,我们将定义它的扭曲图和它的镜像切面。利用扭曲图的镜像切面的面链群,我们将证明Yoshikawa第八步的独立性。因此,我们将建立一个最小生成集的带移动的链接带。
英文摘要:
Yoshikawa moves were introduced at least quarter-century ago and are still actively used by researchers. For any marked graph diagram we will define its twisted diagram and its mirror cut surface. By using a surface-link group of a mirror cut surface of a twisted diagram we will prove the independence of Yoshikawa eighth move. As a consequence we will establish a minimal generating set of band moves for links with bands.
