Fan、Ma与Xing从有限型双参数量子代数出发构造了有向缠结不变量。本文中,我们构建了双参数模与其对应的单参数模之间的显式参数迁移比较关系,并在每个基本有向缠结算子上验证了该比较关系。将标量扩张到公共系数域后,我们证明:若$M_1$是任意有限维可积1型单最高权$U_{v,1}$-模,且其权落在容许格中,$M_t=Φ_t(M_1)$为其迁移模,则对每个有向链环$L$,对应的归一化不变量满足$I_{v,t}^{M_t}(L)=I_{v,1}^{M_1}(L)$。由此,这两个不变量对完全相同的有向链环对赋予相等的值,因此具有相同的区分能力;这涵盖了有限典型型A、B、C、D的向量表示。Sean Clark关于普通与超量子纽结不变量的比较结果,可作为同一迁移原理的特例得到,该原理允许显式标量因子。

英文摘要

Fan, Ma, and Xing constructed oriented-tangle invariants from finite-type two-parameter quantum algebras. In this paper, we construct an explicit parameter-transport comparison between two-parameter modules and their corresponding one-parameter modules, and we verify this comparison on every elementary oriented-tangle operator. After extending scalars to a common coefficient field, we prove that if $M_1$ is any finite-dimensional integrable type-1 simple highest-weight $U_{v,1}$-module whose weights lie in an admissible lattice and $M_t=Φ_t(M_1)$ is its transported module, then for every oriented link $L$, the corresponding normalized invariants satisfy $I_{v,t}^{M_t}(L)=I_{v,1}^{M_1}(L)$. Consequently, the two invariants assign equal values to exactly the same pairs of oriented links and therefore have the same distinguishing power; this includes the vector representations of the finite classical types A, B, C, and D. Sean Clark's comparison of ordinary and super quantum knot invariants is obtained as a specialization of the same transport principle in which explicit scalar factors are allowed.
