Jones多项式的有向局部移动与整除性

Oriented Local Moves and Divisibility of the Jones Polynomial

Paul Drube, Puttipong Pongtanapaisan

摘要:

对于可以被分解成一对定向$n$缠结$S$和$T$的任何虚拟链路$L = S \cup T$,类型$T \mapsto T'$的定向局部移动是以保持$L$的定向的方式用$n$缠结$T'$替换$T$.开发后的琼斯多项式的虚拟链路$L = S \cup T$的$T$的各种(修改)闭包方面的一般分解,我们分析的琼斯多项式的虚拟链路$L_1,L_2$不同,通过本地移动类型$T \mapsto T'$。简洁的整除条件$V(L_1)-V(L_2)$推导出广泛的本地移动,包括$Δ$移动和双$Δ$移动作为特殊情况。由于我们的可除性结果的双重$Δ$ -移动,我们引入了一个必要条件,任何对经典的结是$S$ -等价的。

英文摘要:

For any virtual link $L = S \cup T$ that may be decomposed into a pair of oriented $n$-tangles $S$ and $T$, an oriented local move of type $T \mapsto T'$ is a replacement of $T$ with the $n$-tangle $T'$ in a way that preserves the orientation of $L$. After developing a general decomposition for the Jones polynomial of the virtual link $L = S \cup T$ in terms of various (modified) closures of $T$, we analyze the Jones polynomials of virtual links $L_1,L_2$ that differ via a local move of type $T \mapsto T'$. Succinct divisibility conditions on $V(L_1)-V(L_2)$ are derived for broad classes of local moves that include the $Δ$-move and the double-$Δ$-move as special cases. As a consequence of our divisibility result for the double-$Δ$-move, we introduce a necessary condition for any pair of classical knots to be $S$-equivalent.
