  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. This dependence reduces
the number of field equations and, thus, turns out to be crucial for the
existence of solutions with (A)dS_4 spacetime. Finally, we comment on the
implications of our dS_4 solutions for building gravity duals of Glueball
Inflation.
