Evolution of the cosmological horizons in a universe with countably infinitely many state equations. Journal of Cosmology and Astroparticle Physics 2013(2), pp. 1-151475-7516https://hdl.handle.net/10016/39769This paper is the second of two papers devoted to the study of the evolution of the cosmological horizons (particle and event horizons). Specifically, in this paper we consider a general accelerated universe with countably infinitely many constant state equations, and we obtain simple expressions in terms of their respective recession velocities that generalize the previous results for one and two state equations. We also provide a qualitative study of the values of the horizons and their velocities at the origin of the universe and at the far future, and we prove that these values only depend on one dominant state equation. Finally, we compare both horizons and determine when one is larger than the other.15eng@ 2013 IOP Publishing Ltd and Sissa Medialab srlPhysics of the early universedark energy theoryresearch articleMatemáticashttp://doi.org/10.1088/1475-7516/2013/02/0151215Journal of Cosmology and Astroparticle PhysicsAR/0000033929
