Item Horizon problem and inflation(Indian Academy of Sciences, 1987-06-24) Padmanabhan, T.; Seshadri, T. R.We show that, the part of the universe that is observable today (in principle), could not have evolved out of a domain which was causally connected in the past. This and other issues related to horizon problem in inflationary models are discussed.Item Gaussian states in the De-Sitter spacetime and the evolution of semiclassical density perturbations: 1. Homogeneous mode(Indian Academy of Sciences, 1989-08-08) Seshadri, T. R.; Padmanabhan, T.The evolution of Gaussian quantum states in the de Sitter phase of the early universe is investigated. The potential is approximated by that of an inverted oscillator. We study the origin and magnitude of the density perturbations with special emphasis on the nature of the semiclassical limits.
