    • Ermakov-Lewis invariants and Reid systems 

      Mancas, Stefan C; Rosu Barbus, Haret-Codratian (2014)
      "Reid´s mth-order generalized Ermakov systems of nonlinear coupling constant ? are equivalent to an integrable Emden-Fowler equation. The standard Ermakov-Lewis invariant is discussed from this perspective, and a closed ...

    • Existence of periodic orbits in nonlinear oscillators of Emden-Fowler form 

      Mancas, Stefan C; Rosu Barbus, Haret-Codratian (2016)
      "The nonlinear pseudo-oscillator recently tackled by Gadella and Lara is mapped to an Emden-Fowler (EF) equation that is written as an autonomous two-dimensional ODE system for which we provide the phase-space analysis and ...

    • Radius evolution for bubbles with elastic shells 

      Mancas, Stefan C; Rosu Barbus, Haret-Codratian; Hsieh, Chun-Chung (Elsevier, 2021)
      "We present an analysis of an extended Rayleigh–Plesset (RP) equation for a three dimensional cell of microorganisms such as bacteria or viruses in some liquid, where the cell membrane in bacteria or the envelope (capsid) ...
