Summary of session D2: quantum aspects of cosmology

Martin Bojowald

Show affiliations


This is a summary of talks about quantum aspects of cosmology. Topics involve the properties of quantum matter fields on an expanding spacetime as well as issues in the quantization of gravity itself. This session had three parts, one of which was in a joint session with quantum aspects of black holes (D1) and other quantum aspects (D3). The first block of talks was related to quantum aspects of field theories on a classical spacetime (with possible back-reaction), while the second block dealt in several ways with quantizations of gravity itself. The two talks in the combined session discussed issues in quantum theory on de Sitter space and will therefore be included here in the summary of the first block. For each talk, a reference is given for further details.
