箭头带状图

Arrow ribbon graphs

Robert Bradford, Clark Butler, Sergei Chmutov

摘要:

我们在带状图上引入了一种新的结构,箭头结构。我们将Bollobás-Riordan多项式推广到具有这种结构的带状图。扩展多项式满足压缩-删除关系,并且自然地表现出带状图的部分对偶性。我们构造了一个由虚链路构成的箭头带状图,其扩展的Bollobás-Riordan多项式专门用于最近由H.Dye和L. Kauffman引入的虚链路的箭头多项式.这一结果将经典的Thistlethwaite定理推广到虚链路的箭头多项式。

英文摘要:

We introduce an additional structure on ribbon graphs, arrow structure. We extend the Bollobás-Riordan polynomial to ribbon graph with this structure. The extended polynomial satisfies the contraction-deletion relations and naturally behaves with respect to the partial duality of ribbon graphs. We construct an arrow ribbon graph from a virtual link whose extended Bollobás-Riordan polynomial specializes to the arrow polynomial of the virtual link recently introduced by H.Dye and L.Kauffman. This result generalizes the classical Thistlethwaite theorem to the arrow polynomial of virtual links.
