O(n)矩阵模型中的边界变换算子

Boundary changing operators in the O(n) matrix model

J. -E. Bourgine

摘要:

我们继续研究随机格上稠密O(n)模型中的边界算子。利用矩阵模型描述,导出了插入不同权值JS边界之间的边界算子的共形维数。我们的结果与正规晶格的结果一致。本文将连续极限中的回路方程与边界基环方法得到的边界Liouville三点函数的位移关系联系起来。

英文摘要:

We continue the study of boundary operators in the dense O(n) model on the random lattice. The conformal dimension of boundary operators inserted between two JS boundaries of different weight is derived from the matrix model description. Our results are in agreement with the regular lattice findings. A connection is made between the loop equations in the continuum limit and the shift relations of boundary Liouville 3-points functions obtained from Boundary Ground Ring approach.
