New string vacua from twistor spaces
Alessandro Tomasiello
We find a new family of AdS_4 vacua in IIA string theory. The internal space is topologically either the complex projective space CP^3 or the "flag manifold" SU(3)/(U(1)xU(1)), but…
Reformulating Supersymmetry with a Generalized Dolbeault Operator
Alessandro Tomasiello
The conditions for N=1 supersymmetry in type II supergravity have been previously reformulated in terms of generalized complex geometry. We improve that reformulation so as to comp…
D-branes on Calabi-Yau Manifolds and Superpotentials
Michael R. Douglas, Suresh Govindarajan, T. Jayaraman +1
We show how to compute terms in an expansion of the world-volume superpotential for fairly general D-branes on the quintic Calabi-Yau using linear sigma model techniques, and show…
Projective resolutions of coherent sheaves and descent relations between branes
A. Tomasiello
We notice that, for branes wrapped on complex analytic subvarieties, the algebraic-geometric version of K-theory makes the identification between brane-antibrane pairs and lower-di…
