我们考虑了由SL_2中面群的所有表示组成的特征变化的两种不同的量化。一种是Przytycki-Sikora和Turaev所考虑的skein代数。另一种是契诃夫-福克和卡沙耶夫引入的量子Teichmuller空间。我们构造了一个从skein代数到量子Teichmuller空间的同态,当限制在经典情况下,它对应于这两个代数通过迹函数之间的等价。
We consider two different quantizations of the character variety consisting of all representations of surface groups in SL_2. One is the skein algebra considered by Przytycki-Sikora and Turaev. The other is the quantum Teichmuller space introduced by Chekhov-Fock and Kashaev. We construct a homomorphism from the skein algebra to the quantum Teichmuller space which, when restricted the classical case, corresponds to the equivalence between these two algebras through trace functions.
