We study in detail the moduli space of solutions discovered in LLM relaxing the constraint that guarantees the absence of singularities. The solutions fall into three classes, non-singular, null-singular and time machines with a time-like naked singularity. We study the general features of these metrics and prove that there are actually just two generic classes of space-times — those with null singularities are in the same class as the non-singular metrics. AdS/CFT seems to provide a dual…

1/8 BPS states in AdS/CFT
We study a class of exact supersymmetric solutions of type IIB Supergravity. They have an SO(4) × SU(2) × U(1) isometry and preserve generically 4 of the 32 supersymmetries of the theory.

Bubbling AdS and vacuum string field theory
We show that a family of 1/2-BPS states of N = 4 SYM is in correspondence with a family of classical solutions of VSFT with a B-field playing the role of the inverse Planck constant. We show this

Semi-classical probe strings on giant gravitons backgrounds
In the first part of this paper we study two 2 symmetries of the LLM metric, both of which exchange black and white regions. One of them which can be interpreted as the particle-hole symmetry is the
Minisuperspace quantization of "Bubbling AdS" and free fermion droplets
We quantize the space of 1/2 BPS configurations of type-IIB SUGRA found by Lin, Lunin and Maldacena (hep-th/0409174), directly in supergravity. We use the Crnkovic-Witten-Zuckerman covariant
