We review the remarkable progress that has been made the last 15 years towards the
classification of supersymmetric solutions with emphasis on the description of the bilinears …

We test the robustness of the conditions required for the existence of (supersymmetric)
warped flux anti-de Sitter, de Sitter, and Minkowski backgrounds in supergravity theories …

We classify all warped product de-Sitter backgrounds in heterotic supergravity, up to two
loops. We find that warped $ dS_n $ backgrounds, with $ n\ge 3$, are $\mathbb {R}^{1 …

We investigate deformations of extremal near-horizon geometries in Einstein–Maxwell–
Dilaton theory, including various topological terms, and also in D= 11 supergravity. By …

When Gaussian null coordinates are adapted to a Killing horizon, the near-horizon limit is
defined by a coordinate rescaling and then by taking the regulator parameter ɛ to be small …

We consider the near-horizon geometry of supersymmetric extremal black holes in un-
gauged and gauged 5-dimensional supergravity, coupled to abelian vector multiplets. By …

The supersymmetry of near-horizon geometries in heterotic supergravity is considered. A
necessary and sufficient condition for a solution to preserve more than the minimal N= 2 …

This thesis is devoted to the study of geometric aspects of black holes and integrable
structures in string theory. In the first part, symmetries of the horizon and its bulk extension …

This thesis is devoted to the study of dynamical symmetry enhancement of black hole
horizons in string theory. In particular, we consider supersymmetric horizons in the low …
