Analysis
This article likely delves into the application of the Schwinger-Keldysh formalism, a method used in quantum field theory to study systems out of equilibrium, to cosmological scenarios. The 'cutting rules' probably refer to how to calculate physical observables in this framework. The source, ArXiv, suggests this is a theoretical physics paper, potentially exploring advanced concepts in cosmology and quantum field theory.
Key Takeaways
- •Focuses on applying the Schwinger-Keldysh formalism to cosmology.
- •Investigates 'cutting rules' for calculating observables in cosmological contexts.
- •Likely a highly theoretical paper aimed at researchers in quantum field theory and cosmology.
