Dynamics in nonlocal linear models in the Friedmann-Robertson-Walker metric

Understand

A general class of cosmological models driven by a nonlocal scalar field inspired by the string field theory is studied.

• Using the fact that the considering linear nonlocal model is equivalent to an infinite number of local models we have found an exact special solution of the nonlocal Friedmann equations.
• This solution describes a monotonically increasing Universe with the phantom dark energy.
