Localization of the SFT inspired Nonlocal Linear Models and Exact Solutions

Understand

A general class of gravitational models driven by a nonlocal scalar field with a linear or quadratic potential is considered.

• We study the action with an arbitrary analytic function $F(\Box)$, which has both simple and double roots.
• The way of localization of nonlocal Einstein equations is generalized on models with linear potentials.
• Exact solutions in the Friedmann-Robertson-Walker and Bianchi I metrics are presented.
