Narlikar, J. V.2012-03-062012-03-061963-05-10http://hdl.handle.net/11007/776Cosmological models involving shear and rotation are considered within the framework of Newtonian theorv. It is shown that, under certain assumptions, a differential equation can be obtained for the volume expansion factor. The solutions of this equation show that it is not possible to get non-singular finitely oscillating cosmological models.enCosmological modelNewtonian universesRotationArticle
