Anisotropic Dark Energy and the Generalized Second Law of Thermodynamics
We consider a Bianchi type model in which anisotropic dark energy is
interacting with dark matter and anisotropic radiation. With this scenario, we
investigate the validity of the generalized second law of thermodynamics. It is
concluded that the validity of this law depends on different parameters like
shear, skewness and equation of state.Comment: 12 pages, accepted for publication in Phys. Scr. arXiv admin note:

Validity of the Generalized Second Law of Thermodynamics of the Universe Bounded by the Event Horizon in Holographic Dark Energy Model
In this letter, we investigate the validity of the generalized second law of
thermodynamics of the universe bounded by the event horizon in the holographic
dark energy model. The universe is chosen to be homogeneous and isotropic and
the validity of the first law has been assumed here. The matter in the universe
is taken in the form of non-interacting two fluid system- one component is the
holographic dark energy model and the other component is in the form of dust.Comment: 8 page
