Description
Summary:In the paper On asymptotic solutions of Friedmann equations (Mijajlović et al. 2012), the theory of regularly varying functions in the sense of Karamata is applied in an asymptotic analysis of solutions of Friedmann equations. As is well known, solutions of these equations are used to represent cosmological parameters. Therefore, according to the theory of regularly varying functions all cosmological parameters depend on a function ε(t) such that limt∞1 ε(t) = 0 and which appears in their integral representation. In this paper we derive a differential equation for the parameter ε(t), discuss its solutions and give some physical interpretations. [Projekat Ministarstva nauke Republike Srbije, br. III 44006]
