    • Chebyshev type inequalities with fractional delta and nabla h-sum operators 

      Aslıyüce, Serkan; Güvenilir, Ayşe Feyza (Ankara Üniversitesi Fen Fakültesi, 2021-06-30)
      The aim of this study is to establish new discrete inequalities for synchronous functions using fractional order delta and nabla h-sum operators. We give examples to illustrate our results.
    • Spectrum and symmetries of the impulsive difference equations 

      Bayram, Elgiz; Cebesoy, Şerifenur; Solmaz, Şeyda (Ankara Üniversitesi Fen Fakültesi, 2021-06-30)
      This paper deals with the spectral analysis and symmetries of the second order difference equations with impulse. We determine a transfer matrix and this allows us to investigate the locations of eigenvalues and spectral ...
