周期性WZNW模型的交换代数

On the Exchange Algebra of Periodic WZNW model

利用自由场表示求出了在周期性边界条件下 WZNw模型的r矩阵和交换代数,讨论了交换代数的量子对应以及它在Hamiltonian约化下的行为。

Using the free field representation, we calculate, the r-matrix and classical exchange algebra for WZNW model under periodic boundary condition, and discuss the quantum counterparts of the exchange algebra as well as the performances of the r-matrix and classical exchange algebra under Hamiltonian reductions.
