- W2016603563 abstract "The problem of cosmological graviton creation for homogeneous and isotropic universes with elliptical ($ensuremath{varepsilon}=+1$) and hyperbolical ($ensuremath{varepsilon}=ensuremath{-}1$) geometries is addressed. The gravitational wave equation is established for a self-gravitating fluid satisfying the barotropic equation of state $p=(ensuremath{gamma}ensuremath{-}1)ensuremath{rho}$, which is the source of Einstein's equations plus a cosmological $ensuremath{Lambda}$ term. The time-dependent part of this equation is exactly solved in terms of hypergeometric functions for any value of $ensuremath{gamma}$ and spatial curvature $ensuremath{varepsilon}$. An expression representing an adiabatic vacuum state is then obtained in terms of associated Legendre functions whenever $ensuremath{gamma}ensuremath{ne}frac{2}{3}[frac{(2n+1)}{(2nensuremath{-}1)}]$, where $n$ is an integer. This includes most cases of physical interest such as $ensuremath{gamma}=0, frac{4}{3}, 1$. The mechanism of graviton creation is reviewed and the Bogoliubov coefficients related to transitions between arbitrary cosmic eras are also explicitly evaluated." @default.
