    Hyperbolic space in the Newtonian limit: The cosmological constant 
    Castro-Palacio, Juan Carlos; Fernández de Córdoba, Pedro; Gallego Torromé, R.; Isidro, J.M. (World Scientific, 2022-07-01)
    [EN] In this paper, the cosmological constant and the Boltzmann entropy of a Newtonian Universe filled with a perfect fluid are computed, under the assumption that spatial sections are copies of 3-dimensional hyperbolic space.

    Spherical space in the Newtonian limit: The cosmological constant 
    Isidro, J.M.; Fernández de Córdoba, Pedro; Castro-Palacio, Juan Carlos (World Scientific, 2021-11)
    [EN] We compute the cosmological constant of a spherical space in the limit of weak gravity. To this end, we use a duality developed by the present authors in a previous work. This duality allows one to treat the Newtonian ...

    The cosmological constant of emergent spacetime in the Newtonian approximation 
    Castro-Palacio, J. C.; Fernández de Córdoba, Pedro; Isidro, J.M. (World Scientific, 2020-10)
    [EN] We present a simple quantum-mechanical estimate of the cosmological constant of a Newtonian Universe. We first mimic the dynamics of a Newtonian spacetime by means of a nonrelativistic quantum mechanics for the matter ...
