Quantization of linearized gravity in cosmological vacuum spacetimes

Research output: Contribution to journalArticlepeer-review


Linearized Einstein gravity (with possibly nonzero cosmological constant) is quantized in the framework of algebraic quantum field theory by analogy with Dimock’s treatment of electromagnetism [Rev. Math. Phys. 4 (1992) 223–233]. To achieve this, the classical theory is developed in a full, rigorous and systematic fashion, with particular attention given to the circumstances under which the symplectic product is weakly non-degenerate and to the related question of whether the space of solutions is separated by the classical observables on which the quantum theory is modelled.
