摘要: The author investigates the change in event-horizon area cosmological models that depart slightly from de Sitter space. If gravitational source is a perfect inviscid fluid satisfying dominant energy condition, proved to be non-decreasing. viscous, can decrease, but attendant generation of entropy ensures generalised second law thermodynamics remains unviolated.
