Abstract: (arXiv)
A simple set of diagrammatic rules is formulated for perturbative evaluation of ``in-in" correlators, as is needed in cosmology and other nonequilibrium problems. These rules are both intuitive, and efficient for calculational purposes.Note:
- 7 pages, 3 figures
- field theory: scalar
- phi**n model: 3
- space-time: Robertson-Walker
- propagator
- perturbation theory: higher-order
