    • Barotropic FRW cosmologies with Chiellini damping 

      Rosu Barbus, Haret-Codratian; Mancas, Stefan C; Chen, Pisin (2015)
      "It is known that barotropic FRW equations written in the conformal time variable can be reduced to simple linear equations for an exponential function involving the conformal Hubble rate. Here, we show that an interesting ...

    • Barotropic FRW cosmologies with Chiellini damping in comoving time 

      Rosu Barbus, Haret-Codratian; Mancas, Stefan C; Chen, Pisin (2015)
      "For nonzero cosmological constant ?, we show that the barotropic FRW cosmologies as worked out in the comoving time lead in the radiation-dominated case to scale factors of identical form as for the Chiellini dissipative ...
