Taming the infrared in de Sitter space: autonomous equations, stochastic approach, and Borel resummation
Alexander Kamenshchik, Polina Petriakova, Tereza Vardanyan
We investigate the divergent perturbative series of correlation functions for a massless, self-interacting scalar field in de Sitter space. First, we use our previously proposed me…

From the Fokker-Planck equation to perturbative QFT's results in de Sitter space
Alexander Kamenshchik, Polina Petriakova
A technique to build perturbative series for the spectator field's correlation functions in de Sitter space through the Fokker-Planck equation is proposed. We derive from the first…

Dynamics of a homogeneous and isotropic space in pure cubic f(R) gravity
P. M. Petryakova
We consider a possible ways of the dynamics of a homogeneous and isotropic space described by the FLRW metric in the framework of cubic f(R) gravity in the absence of matter. This…
