Existence and uniqueness of solutions of the semiclassical Einstein equation in cosmological models
Paolo Meda, Nicola Pinamonti, Daniel Siemssen
We prove existence and uniqueness of solutions of the semiclassical Einstein equation in flat cosmological spacetimes driven by a quantum massive scalar field with arbitrary coupli…
