عنوان Logarithmic corrected polynomial f(R) inflation mimicking a cosmological constant
نوع پژوهش مقاله چاپ شده
کلیدواژه‌ها Modified gravity; inflation; Planck data
چکیده In this paper, we consider an inflationary model of f(R) gravity with polynomial form plus logarithmic term. We calculate some cosmological parameters and compare our results with the Planck 2015 data. We find that presence of both logarithmic and polynomial corrections is necessary to yield slow-roll condition. Also, we study critical points and stability of the model to find that it is a viable model.
