G-structures for black hole near-horizon geometries
Andrea Legramandi, Niall T. Macpherson, Achilleas Passias
We derive necessary and sufficient conditions for warped AdS solutions of Type II supergravity to preserve supersymmetry, in terms of bispinors. Such solutions gen…

Superstrings on Penrose limits of AdS solutions
Achilleas Passias
We consider the Penrose limit of AdS solutions of massive Type IIA supergravity. The resulting pp-wave geometry is supported by RR and NSNS fields. We quantize the Green--Schwa…
