For each finite split semisimple tensor category C, the canonical Tannaka duality gives a quantum group (face algebra) whose comodule category is equivalent to C. The duality gives a unified understanding of tensor categories arising from mathematics and physics, and also, it gives a new picture of the representation theory of the ordinary groups. By applying the duality and other techniques in the quantum group theory, we obtained the following results.1. We showed that the quantum ej-symbo, is a sum of the partition functions of the ABF mode, of finite size. Also we gave a simple summation formula for the ordinary 6j-symbols.2. By using the duality (or rather the canonical fiber functor), we constructed a bases for invariants and semiinvariants of binary quadratics and binary cubics.3. For each tensor products of two irreducible representations of the general linear group, we gave their explicit irreducible decomposition at the module level.4. We classified the braiding and th'e ribbon structure on each quantum classica, groups and the tensor category of type A of level L.5. For each linearly reductive matrix group G, we give an "economical" inverse matrix formula for each elements of G.

对于每个有限分裂半单张量范畴C，正则Tannaka对偶给出一个量子群（面代数），其余模范畴等价于C。对偶性给出了对产生于数学和物理的张量范畴的统一理解，也给出了普通群表示论的新图景。利用量子群论中的对偶性等技巧，我们得到了如下结果.我们表明，量子ej-symbo，是ABF模式的配分函数的总和，有限的大小。并给出了普通6 j-符号的一个简单求和公式。利用对偶性（或者说典范纤维函子），我们构造了二元二次和二元二次的不变量和半不变量的基.对于一般线性群的两个不可约表示的每个张量积，我们给出了它们在模水平上的显式不可约分解。4.我们对每个量子经典群和L.5类A型张量范畴上的辫状和带状结构进行了分类。对任意线性可约矩阵群G，给出了G中各元素的“经济”逆矩阵公式。
