Pre-potential in the $Ad{S}_5\times S^5$ Type IIB superspace

We found the pre-potential in the superspace with $Ad{S}_5\times S^5$ background. The pre-potential appears as part of the vielbeins, without derivatives. The space-cone gauge destroys the bulk Lorentz covariance, but still preserves boundary Lorentz covariance (projective superspace) $SO(3,1)\otimes SO(4)$, i.e. symmetries of boundary CFT are manifest.
