• 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 ...
