    Newtonian universes with shear and rotation
    (Wiley-Blackwell, 1963-05-10) Narlikar, J. V.
    Cosmological 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.

    Neutrinos and the arrow of time in cosmology
    (Royal Society, 1962-06-05) Narlikar, J. V.
    Hogarth's approach to the time-symmetric electrodynamics of Wheeler & Feynman is extended to apply to the neutrinos. It is shown that in some cosmological models neutrinos travelling both into the past and the future exist whereas in others only those going into the the future can exist. The Einstein-de Sitter and the steady-state models are the respective examples of the two cases. An interesting way of testing the various cosmologies by means of neutrino emitters and receivers is suggested.
