Einstein static universe on the brane supported by extended Chaplygin gas

Understand

We study the cosmological models in which an extended Chaplygin gas universe is merged with the braneworld scenario.

• In particular, we examine the realization of Einstein static universe on the brane embedded in a non-constant curvature bulk space and perform a detailed perturbation analysis.
• We extract the stability conditions and find their impacts on the geometric equation of state parameter and the spatial curvature of the universe.
