Abstract: In this paper, we study the future global existence and late-time behaviour of the Einstein-Boltzmann system with Bianchi I symmetry and a positive cosmological constant Λ>0. For the Boltzmann equation, we consider the scattering kernel…

Abstract: In this paper, we revisit the classical mechanism to produce [Formula: see text]-dimensional spacetimes via Kaluza–Klein compactification. We made the assumption that the [Formula: see text]-dimensional bulk geometry [Formula: see text] admits a Homothetic Vector…

DOI: 10.1142/s0218271819300039
Abstract: A review is given of the various approaches to and expressions for total energy–momentum and mass in the presence of a positive cosmological constant in Einstein’s field equations, together with a discussion of the key…
