Description
In this talk I will analyse a variety of Euclidean saddles in the gravitational path integral, with asymptotic AdS boundary conditions, in a class of Einstein-Scalar-Maxwell models.
These include single boundary solutions, usual and wineglass wormholes, as well as more exotic (quasi)-oscillatory saddles. Some of these Euclidean backgrounds can be continued to Lorentzian FRW universes that contain an early period of inflation.
