Implications of the Ornstein-Uhlenbeck-like fractional differential equation in cosmology

In this paper we introduce a generalized fractional scale factor and a time-dependent Hubble parameter obeying an “Ornstein-Uhlenbeck-likefractional differential equation” which serves to describe the accelerated expansion of a non-singular universe with and without the presenceof scalar fields. Som...
