# On the Problem of Initial Conditions for Inflation

@article{Linde2018OnTP, title={On the Problem of Initial Conditions for Inflation}, author={Andrei Linde}, journal={Foundations of Physics}, year={2018}, volume={48}, pages={1246-1260} }

I review the present status of the problem of initial conditions for inflation and describe several ways to solve this problem for many popular inflationary models, including the recent generation of the models with plateau potentials favored by cosmological observations.

In construction of an inflationary model, one usually assumes that the matter sector of the gravitational action is minimally coupled to the background. It means that the matter (inflaton) part of…
