The Instabilities of Bianchi Type IX Einstein Static Universes    [PDF]

John D. Barrow, Kei Yamamoto

We investigate the stability of the Einstein static universe as a non-LRS
Bianchi type IX solution of the Einstein equations in the presence of both
non-tilted and tilted fluids. We find that the static universe is unstable to
homogeneous perturbations of Bianchi type IX to the future and the past.
