Chaotic inflation in spatially homogeneous Bianchi type V space-time

Chaotic inflationary scenario in spatially homogeneous Bianchi type V space-time following Linde (Phys. Lett. B, 129, 177 (1983). doi:10.1016/0370-2693(83)90837-7) and the condition R³=e^3H₀t based on theory of super cooling during the cosmological phase transition proposed by Kirzhnits and Linde (Ann. Phys. 101, 195 (1976). doi:10.1016/0003-4916(76)90279-7), is discussed. It has been found that the model represents anisotropic phase of the Universe in general but at late time, it isotropizes. The deceleration parameter q = -1 indicates that the model leads to de Sitter space-time. It is found that inflationary parameters, namely, slow roll parameters, and anisotropic parameters are in excellent agreement with the Planck Collaboration's 2013 results (Astron. Astrophys. 571, A22 (2014). doi:10.1051/0004-6361/201321569). (author)
