Bertotti-Robinson and soliton string solutions of $D=5$ minimal supergravity

Understand

We report on a series of new solutions to five-dimensional minimal supergravity.

• Our method applies to space-times with two commuting Killing symmetries and consists in combining dimensional reduction on two-spaces of constant curvature with reduction on a two-torus.
• The first gives rise to various generalized Bertotti-Robinson solutions supported by electric and magnetic fluxes, which presumably describe the near-horizon regions of black holes and black rings (strings).
• The second provides generating techniques based on U-duality of the corresponding three-dimensional sigma model.
