This paper investigates the relation between colored HOMFLY-PT and Kauffman homology, \({{\,\mathrm{SO}\,}}(N)\) quantum 6j-symbols, and (at)-deformed \(F_K\). First, we present a simple rule of grading change which allows us to obtain the [r]-colored quadruply graded Kauffman homology from the \([r^2]\)-colored quadruply graded HOMFLY-PT homology for thin knots. This rule stems from the isomorphism of the representations \((\mathfrak {so}_6,[r]) \cong (\mathfrak {sl}_4,[r^2])\). Also, we find the relationship among A-polynomials of \({{\,\mathrm{SO}\,}}\) and \({{\,\mathrm{SU}\,}}\) type coming from a differential on Kauffman homology. Second, we put forward a closed-form expression of \({{\,\mathrm{SO}\,}}(N)(N\ge 4)\) quantum 6j-symbols for symmetric representations and calculate the corresponding \({{\,\mathrm{SO}\,}}(N)\) fusion matrices for the cases when representations

关于结,补码和6 j-符号

本文研究了彩色HOMFLY-PT与Kauffman同源性,\({{\,mathrm {SO} \,}}(N)\)量子6 j符号和(a,  t)变形\( F_K \)。首先,我们给出一个简单的渐变变化规则,该规则使我们能够从\([r ^ 2] \)色四重渐变HOMFLY-PT同源性获得薄的结的[ r ]色四重渐变Kauffman同源性。该规则源于表示\((\ mathfrak {so} _6,[r])\ cong(\ mathfrak {sl} _4,[r ^ 2])\)的同构。此外,我们发现\({{\,\ mathrm {SO} \,}} \)的A-多项式与\({{\,\ mathrm {SU} \,}} \)类型来自考夫曼同源性的差异。其次,我们为对称表示提出了\({{\,\ mathrm {SO} \,}}(N)(N \ ge 4)\)量子6 j-符号的闭式表达式,并计算了相应的\ ({{\,\ mathrm {SO} \,}}(N)\)融合矩阵
