EL-NABULSI, Rami Ahmad. Implications of the Ornstein-Uhlenbeck-like fractional differential equation in cosmology. Rev. mex. fis. [online]. 2016, vol.62, n.3, pp.240-250. ISSN 0035-001X.

In this paper we introduce a generalized fractional scale factor and a time-dependent Hubble parameter obeying an “Ornstein-Uhlenbeck-like fractional differential equation” which serves to describe the accelerated expansion of a non-singular universe with and without the presence of scalar fields. Some hidden cosmological features were captured and discussed consequently.

Palavras-chave : FRW flat cosmology; generalized fractional scale factor; Ornstein-Uhlenbeck-like fractional differential equation; Mittag-Leffler function; Gauss-Bonnet invariant.
