  • Astrophysical consequences of barytinos 
    Sivaram, C (Springer, 1983-01)
    Some astrophysical consequences of the newly introduced barytino (massless fermions having baryon number, analogous to the massless neutrino having lepton number) are considered. It is pointed out that the existence of ...
  • Energy enigmas in the early universe and related problems in Newtonian cosmology 
    Sivaram, C (Springer, 1988-01)
    Some paradoxical situations regarding the balance between the different forms of energy present and the velocities of expansion in the early stages of the big bang are discussed. Solutions are suggested in the framework ...
  • Evolution of the Universe through the Planck epoch 
    Sivaram, C (Springer, 1986-08)
    The problem of the Universe emerging out of the Planck epoch is discussed. It is pointed out that an earlier exponential expansion phase well before the onset of the GUTs phase transition is essential. Such an expansion ...
  • Neutral fermions as the missing mass matter in galactic halos 
    Datta, B; Sivaram, C; Ghosh, S. K (Springer, 1985-04)
    Several independent considerations which rule out the hypothesis that the missing mass in galactic halos is composed of massive neutral fermions such as neutrinos, gravitinos, or photinos are discussed. It is found that ...
  • Neutron oscillation and the primordial magnetic field 
    Sivaram, C; Krishan, V (Gordon and Breach Science Publishers, 1983)
    The phenomenon of neutron-antineutron oscillations, recently proposed as a novel consequence of grand unified theories, permits limits to be placed on any primordial field present during the nucleosynthetic stage of the ...
  • Nonlinear curvature Lagrangians and extended inflation in the early universe 
    Sivaram, C; Campanelli, M (Springer, 1992-08)
    Theories with Lagrangians nonlinear in the curvature scalar can be reduced by appropriate transformations to a form similar to the Brans-Dicke model. This may enable us to have extended inflation in the early universe ...
  • On structure formation in the universe 
    Satya Narayanan, A (Springer, 1994-12)
    The formation of structures in the universe is one of the most challenging problems of cosmology. In this paper, an attempt to explain the formation of galaxies through the generation of vortices (with dissipation) in an ...
  • Torsion and inflation 
    Sivaram, C; De Sabbata, V (Springer, 1991-02)
    The effects of torsion in the early universe on the subsequent evolution are investigated theoretically. The focus is on the simple Einstein-Cartan generalization of conventional big-bang cosmology studied by de Sabbata ...
