Description

I would like to discuss recent results in well-known (and not so much) techniques to calculate correlation functions in de Sitter space and beyond. The main focus of my talk is the connection of the stochastic formalism to perturbative QFT's results in curved spacetime.

Based on arXiv: [2410.16226] and work in progress.
