On the Stability of Jordan-Brans-Dicke Static Universe
  In this work we study the stability of the Jordan-Brans-Dicke (JBD) static
universe. This is motivated by the possibility that the universe might have
started out in an asymptotically JBD static state, in the context of the so
called emergent universe scenario. We extent our previous results on stability
of JBD static universe by considering spatially homogeneous Bianchi type IX
anisotropic perturbation modes and by including more general perfect fluids.
Contrary to general relativity, we have found that the JBD static universe,
dominated by a standard perfect fluid, could be stable against isotropic and
anisotropic perturbations. The implications of these results for the initial
state of the universe and its pre-inflationary evolution are discussed.
