Operator Method and Recursion Relations for Inflationary Correlator
arXiv:1812.00322 · doi:10.1088/1475-7516/2019/03/042
Abstract
We develop the systematics for applying operators on Minkowski correlation functions to get the inflationary correlation functions. Simple structures and recursion relations are known for Minkowski correlation functions. Using the operator technique, various novel recursion relations for inflationary correlation functions are obtained.
