De Sitter Space in Gauge/Gravity Duality

Understand

We investigate gauge/gravity duality for gauge theories in de Sitter space.

• More precisely, we study a five-dimensional consistent truncation of type IIB supergravity, which encompasses a wide variety of gravity duals of strongly coupled gauge theories, including the Maldacena-Nunez solution and its walking deformations.
• We find several solutions of the 5d theory with dS_4 spacetime and nontrivial profiles for (some of) the scalars along the fifth (radial) direction.
• In the process, we prove that one of the equations of motion becomes dependent on the others, for nontrivial warp factor.
