Singularity-free Cosmological Solutions with Non-rotating Perfect Fluids
A. K. Raychaudhuri
The paper establishes the result that solutions of the type described in the title of the article are only those that have been already presented in the literature. The procedure a…

A new singularity theorem in relativistic cosmology
A. K. Raychaudhuri
It is shown that if the timelike eigenvector of the Ricci tensor be hypersurface orthogonal so that the space time allows a foliation into space sections then the space average of…

Oscillating non-singular relativistic spherical model
Naresh Dadhich, A. K. Raychaudhuri
A particular choice of the time function in the recently presented spherical solution by Dadhich [1] leads to a singularity free cosmological model which oscillates between two reg…
