我们推广了Arxiv：1105.5165的结果，其中基于ADS/CFT，提出了定义在有边界流形上的共形场论的全息描述。我们在条形、球和含时边界上构造了共形场理论的重力对偶。我们证明了一个任意维的全息g-定理。作为一个特例，我们可以在三维共形场理论中定义“边界中心电荷”，并且我们的全息g-定理认为，在RG流的作用下，边界中心电荷减小。我们还计算了全息单点函数，并证实其标度性质与场论计算一致。最后，给出了在ADS4×CP3中插入8个方向面的弦理论嵌入全息图的例子。
We expand the results of arXiv: 1105.5165, where a holographic description of a conformal field theory defined on a manifold with boundaries (so called BCFT) was proposed, based on AdS/CFT. We construct gravity duals of conformal field theories on strips, balls and also time-dependent boundaries. We show a holographic g-theorem in any dimension. As a special example, we can define a ‘boundary central charge’in three dimensional conformal field theories and our holographic g-theorem argues that it decreases under RG flows. We also computed holographic one-point functions and confirmed that their scaling property agrees with field theory calculations. Finally, we give an example of string theory embedding of this holography by inserting orientifold 8-planes in AdS 4× CP 3.
