    • Barotropic FRW cosmologies with Chiellini damping 

      Rosu Barbus, Haret-Codratian; Stefan C. Mancas; Pisin Chen (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 ...
    • Integrable equations with Ermakov-Pinney nonlinearities and Chiellini damping 

      Stefan C. Mancas; Rosu Barbus, Haret-Codratian (2015)
      "We introduce a special type of dissipative Ermakov-Pinney equations of the form v?? + g(v)v? + h(v) = 0, where h(v) = h0(v) + cv?3 and the nonlinear dissipation g(v) is based on the corresponding Chiellini integrable Abel ...
