摘要

对于一个简化的交替曲面连接图,我们用多项式不变量的系数来约束D$的扭数。为此,我们引入了Krushkal定义的同调Kauffman括号的推广。结合Futer, Kalfagianni和Purcell的工作,这就产生了一类交替曲面连杆的双曲体积的边界。

Homological polynomial coefficients and the twist number of alternating surface links
For $D$ a reduced alternating surface link diagram, we bound the twist number of $D$ in terms of the coefficients of a polynomial invariant. To this end, we introduce a generalization of the homological Kauffman bracket defined by Krushkal. Combined with work of Futer, Kalfagianni, and Purcell, this yields a bound for the hyperbolic volume of a class of alternating surface links in terms of these coefficients.
