TASI lectures: special holonomy in string theory and M-theory
Steven S. Gubser
A brief, example-oriented introduction is given to special holonomy and its uses in string theory and M-theory. We discuss A_k singularities and their resolution; the construction…
Supersymmetry and F-theory realization of the deformed conifold with three-form flux
Steven S. Gubser
It is shown that the deformed conifold solution with three-form flux, found by Klebanov and Strassler, is supersymmetric, and that it admits a simple F-theory description in terms…
Instability of charged black holes in anti-de Sitter space
Steven S. Gubser, Indrajit Mitra
We exhibit a tachyonic mode in a linearized analysis of perturbations of large anti-de Sitter Reissner-Nordstrom black holes in four dimensions. In the large black hole limit, and…
Dynamics of D-brane Black Holes
Steven S. Gubser
We explore the interplay between black holes in supergravity and quantum field theories on the world-volumes of D-branes. A brief summary of black hole entropy calculations for D-b…
Dilaton-driven confinement
Steven S. Gubser
We derive a solution of type IIB supergravity which is asymptotic to AdS_5 x S^5, has SO(6) symmetry, and exhibits some of the features expected of geometries dual to confining gau…
