Abstract

In this paper we discuss thermodynamics of interacting ghost dark energy models in a flat FRW universe. During the discussion our attention will be concentrated on nonlinear interactions of particular form. In the considered models dark matter is assumed to be a pressureless matter and allows to complete the darkness of the low-redshift universe. Ghost dark energy it is one of the models of dark energy among others with an explicitly given energy density as a function of the Hubble parameter of the universe. Our study aims to have a contribution towards recently suggested interacting ghost dark energy models.
