Isotropic inhomogeneous metric

**ridox** · Feb16-10, 11:29 AM

Hi everyone,

I have been looking for a spherical symetric, static, isotropic and inhomogeneous metric, so far I had found the LTB metric wich could be one possible candidate, but i was thinking more like a inhomogeneous FRW metric. I appreciate your suggestions and thank you for your time.

This paper discusses an inhomogenous cosmological model.

arXiv:astro-ph/0506534 v2 22 Jun 2006.

I haven't read it since it was published by FermiLab. ( I hope that pedigree is good enough to count as a serious journal ).

They give an inhomogeneous FRW universe, meaning that the metric is dependent on time so it is not definitely static. This can be seen clearly from the line element they are woking with from the beginning that has a factor $LaTeX Code: h(\\textbf{x},t)$ multiplied by all spatial components, i.e. $LaTeX Code: g_{ij}.$
