Interacting dark sector and the coincidence problem within the scope of LRS Bianchi type I model

Abstract

© 2018, Springer Science+Business Media B.V., part of Springer Nature. It is shown that a suitable interaction between dark energy and dark matter in locally rotationally symmetric (LRS) Bianchi-I space-time can solve the coincidence problem and not contradict the accelerated expansion of present Universe. The interaction parameters are estimated from observational data.
