    • Convergence of solutions of nonautonomous Nicholson's Blowflies model with impulses 

      Demirci, Elif; Karakoç, Fatma (Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
      This paper deals with a nonautonomous Nicholson's blowflies model with impulses. It is shown that under the proper conditions every positive solution of the model approaches to a constant as t tends to infinity.
    • Principal functions of impulsive difference operators on semi axis 

      Erdal, İbrahim; Yardımcı, Şeyhmus (Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
      In this paper, we investigate the continuous spectrum and resolvent operator of a second-order difference operator with an impulsive condition. Then, under certain conditions, we prove finiteness of eigenvalues, spectral ...
