    • Chaplygin-gas solutions of f(R) gravity 

      Elmardi, Maye; Abebe, Amare; Tekola, Abiy (World Scientific Publishing, 2016)
      We explore exact f(R) gravity solutions that mimic Chaplygin-gas inspired CDM cosmology. Starting with the original, generalized and modified Chaplygin gas equations of state, we reconstruct the forms of f(R) Lagrangians. ...
