Aspects of Nonlinear Perturbations in Cosmological Models
Speaker(s): Bojan Losic
Abstract: I discuss two instances in which nonlinear perturbations in cosmological models are important. First, in de Sitter space-time, the bare necessity that the perturbations should be part of a consistent Taylor expansion of the field equations leads to the requirement, using the 'linearization stability... read more
