Inflação cosmológica não-comutativa.

Abstract

In recent years, there has been growing interest in studies that address noncommutative geometry applied to space-time in some cosmological scenarios. This dissertation seeks to present an introduction to some aspects of noncommutative cosmology, in particular, we will present some recent works that address topics of inflationary cosmology, noncommutative quantum field theory and Thermodynamics of noncommutative gas. In the era of cosmological inflation, the Universe presents thermodynamic conditions that can be ascertained through the theoretical framework of TQCNC. A noncommutative gas diluted to a high temperature T = 1014GeV ≃ 1027K described by the quantities ω(σ, θ, β) filled the Universe at this epoch. Recent works have investigated some possible inflationary scenarios of the primordial Universe arising from the analysis of the state equation p/ρ = ω(σ, θ, β) and by modifying the parameters σ, θ and β, analyzed the behavior of the gas when the Universe entered the accelerated expansion phase.
