  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.
