• Eigenvalue problems, spectral parameter power series, and modern applications 

      Rosu Barbus, Haret-Codratian (2015)
      "Our review is dedicated to a wide class of spectral and transmission problems arising in di?erent branches of applied physics. One of the main di?culties in studying and solving eigenvalue problems for operators with ...
    • Integrable Abel equations and Vein's Abel equation 

      Mancas, Stefan C; Rosu Barbus, Haret-Codratian (2016)
      "We first reformulate and expand with several novel findings some of the basic results in the integrability of Abel equations. Next, these results are applied to Vein's Abel equation whose solutions are expressed in terms ...
