我们从体积理论和边界理论两个角度研究了定域闭弦快子在ADS上的凝聚。我们首先将AdS5/k的已知结果推广到ADS3/k情形，提出了ADS3/k衰变为ADS3/k‘，其中k’<；k。从整体的观点出发，我们得到了一个含时间的引力解，数值描述了Ads3/k的衰变过程。从对偶规范理论的观点出发，计算了规范理论真空的Casimir能量，发现它们的值与对偶几何的质量是完全相同的，即使它们处于不同的Hooft耦合参数范围内.我们还考虑了AdS5，AdS5/k的衰变与RT×S3/k上的对偶规范理论真空之间的跃迁是对偶的.我们利用RT×S2上的瞬子解构造了描述跃迁的瞬子解.
We study the condensation of localized closed string tachyons on AdS orbifolds both from the bulk and boundary theory viewpoints. We first extend the known results for AdS5/k to AdS3/k case, and we proposed that the AdS3/k decays into AdS3/k' with k' < k. From the bulk viewpoint, we obtain a time-dependent gravity solution describing the decay of AdS orbifold numerically. From the dual gauge theory viewpoint, we calculated the Casimir energies of gauge theory vacua and it is found that their values are exactly the same as the masses of dual geometries, even though they are in different parameter regimes of 't Hooft coupling. We also consider AdS5 orbifold. The decay of AdS5/k is dual to the transition between the dual gauge theory vacua on Rt × S3/k, parametrized by different holonomies along the orbifolded spatial cycle. We constructed the instanton solutions describing the transitions by making use of instanton solutions on Rt × S2.
