abstract

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.

    The FL equations are claimed to reduce to four inequivalent versal unfoldings that generate nonsmooth, singularity-free 'metamorphosing' cosmologies.
