A geometric approach to D-branes in group manifolds
Sonia Stanciu
This is a brief review of some recent results on the geometric approach to symmetric D-branes in group manifolds, both twisted and untwisted. We describe the geometry of the gluing…
Chern-Simons Vortices in Supergravity
M. Abou-Zeid, H. Samtleben
We study supersymmetric vortex solutions in three-dimensional abelian gauged supergravity. First, we construct the general U(1)-gauged D=3, N=2 supergravity whose scalar sector is…
Intersecting Brane Worlds on Tori and Orbifolds
Ralph Blumenhagen, Boris Kors, Dieter Lust +1
We review the construction and phenomenology of intersecting brane worlds. The breaking of chiral and supersymmetry together with a reduction of gauge symmetry by introducing D-bra…
Fluxes and Branes in Type II Vacua and M-theory Geometry with G(2) and Spin(7) Holonomy
Gottfried Curio, Boris Kors, Dieter Lust
We discuss fluxes of RR and NSNS background fields in type II string compactifications on non-compact Calabi-Yau threefolds together with their dual brane description which involve…
D-instanton probes of N=2 non-conformal geometries
Francesco Fucito, Jose F. Morales, Alessandro Tanzini
D-instanton calculus has proved to be able to probe the AdS near horizon geometry for D-branes systems which, when decoupled from gravity, yield four dimensional superconformal…
On the Supersymmetric Index of the M-theory 5-brane and Little String Theory
G. Bonelli
We propose a six-dimensional framework to calculate the supersymmetric index of M-theory 5-branes wrapped on a six-manifold with product topology , where is a…
