A cosmological model formulated in Lyra geometry incorporating Ricci dark energy and a deceleration parameter that varies linearly

Abstract

This research focuses on exploring the dynamics of a cosmos model under the influence of Ricci dark energy within the framework of modified Lyra geometry. The modified field equations of Einstein for Lyra’s geometry are introduced, and specific solutions are obtained for a Big Rip cosmos scenario. Additionally, various physical and geometrical aspects of the cosmos are comprehensively investigated and discussed.
