本文讨论一般全息共形场论中有边界或有缺陷的测地线维滕图。在边界或亏损共形场论中，两点函数是非平凡的，可以用两种不同的方式分解成共形块：环境通道分解和边界通道分解。在我们以前的工作[A。Karch和Y. Sato，J. High Energy Phys. 09（2017）121.JHEPFG 1029 -847910.1007/JHEP 09（2017）121]我们只考虑相同算子的两点函数。我们推广我们以前的工作的情况下，运营商在两点函数是不同的。我们得到了不同算子的两点函数的两种不同的分解。
In this paper we discuss geodesic Witten diagrams in general holographic conformal field theories with boundary or defect. In boundary or defect conformal field theory, two-point functions are nontrivial and can be decomposed into conformal blocks in two distinct ways; ambient channel decomposition and boundary channel decomposition. In our previous work [A. Karch and Y. Sato, J. High Energy Phys. 09 (2017) 121.JHEPFG1029-847910.1007/JHEP09(2017)121] we only consider two-point functions of same operators. We generalize our previous work to a situation where operators in two-point functions are different. We obtain two distinct decomposition for two-point functions of different operators.
