[ 1 ] - بررسی شکافتگی کوچک و دیگر تکینگیهای آینده عالم و برقراری قانون دوم ترمودینامیک در نظریه
The future singularities are possible in a universe that is described by F(R) theory. In previous studies the occurrence of the singularities in F(R) theory have been considered by using a special function for the Hubble parameter and calculating the F(R) function for each of the singularities. Using the specified Hubble parameter causes some difficulties in the study of the second law of therm...
[ 2 ] - گرانش به عنوان نیروی آنتروپی و تاثیر آن بر تکینگیهای معادلات فریدمن
Interpretation of gravity as entropic force makes some corrections in Friedmann equations. According to calculations of Easson, Frampton and Smooth, the entropic force addss correction terms to Friedmann equations. It’s shown that these corrections change the second type of singularity to the third one in Friedmann equations. Considering Friedmann equations, even without entropic force at leas...
