Abstract
In this work we study the stability of the Jordan-Brans-Dicke(JBD) static universe. This is motivated by the possibility thatthe universe might have started out in an asymptotically JBDstatic state, in the context of the so called emergent universescenario.We extent our previous results on stability of JBD static universeby considering spatially homogeneous Bianchi type IX anisotropicperturbation modes and by including more general perfect fluids.Contrary to general relativity, we have found that the JBD staticuniverse, dominated by a standard perfect fluid, could be stableagainst isotropic and anisotropic perturbations. The implicationsof these results for the initial state of the universe and itspre-inflationary evolution are discussed.
