在AdS中，涂抹反膜极化
Smeared antibranes polarise in AdS
摘要：
在最近的文献中，有人质疑通量喉道中反膜的局部反反应是否能引起微扰的膜通量衰变。这一点的大多数证据可以从在6-p紧致方向上涂抹的D 6膜和Dp膜中收集到，这与这些情况下缺乏有限温度解是一致的。文献中的解具有平坦的世界体积几何和非紧的横截空间。在本文中，我们考虑会发生什么时，世界体积是AdS和横向空间是紧的。我们表明，在这些情况下膜极化平滑了通量奇异性，这是一个迹象表明，膜通量衰减被阻止。这与膜通量衰变后宇宙学常数的负值减小的事实相一致。我们的结果推广了最近关于D 6膜上AdS_7解的结果到Dp膜上AdS_（p+1）解.我们证明了AdS解的超对称性依赖于p的非平凡性。
英文摘要：
In the recent literature it has been questioned whether the local backreaction of antibranes in flux throats can induce a perturbative brane-flux decay. Most evidence for this can be gathered for D6 branes and Dp branes smeared over 6-p compact directions, in line with the absence of finite temperature solutions for these cases. The solutions in the literature have flat worldvolume geometries and non-compact transversal spaces. In this paper we consider what happens when the worldvolume is AdS and the transversal space is compact. We show that in these circumstances brane polarisation smoothens out the flux singularity, which is an indication that brane-flux decay is prevented. This is consistent with the fact that the cosmological constant would be less negative after brane-flux decay. Our results extend recent results on AdS_7 solutions from D6 branes to AdS_(p+1) solutions from Dp branes. We show that supersymmetry of the AdS solutions depend on p non-trivially.
