Khovanov同调与交错纽结的扭数

Khovanov Homology and the Twist Number of Alternating Knots

Robert G. Todd

摘要:

X.S. Lin和O.达斯巴赫证明了交替纽结的琼斯多项式的第二个和倒数第二个系数的绝对值之和等于纽结的捻数。本文利用Khovanov同调给出了其结果的一个新的证明。证明是通过归纳的交叉数使用长的准确序列在Khovanov同调对应的考夫曼括号绞关系。

英文摘要:

X.S. Lin and O. Dasbach proved that the sum of the absolute value of the second and penultimate coefficients of the Jones polynomial of an alternating knot is equal to the twist number of the knot. In this paper we give a new proof of their result using Khovanov homology. The proof is by induction on the number of crossings using the long exact sequence in Khovanov homology corresponding to the Kauffman bracket skein relation.
