• The Theory of Cosmological Perturbations2026
• Perturbative Analysis of Singularity-Free Cosmological Solutions in Unimodular Kaluza–Klein Theory2026
• Anisotropic Bianchi-I cosmological model in non-conservative unimodular gravity2026
• Neutron stars in Rastall gravity2015 · аннотациясвернуть

  We calculate static and spherically symmetric solutions for the Rastall modification of gravity to describe neutron stars (NS). The key feature of the Rastall gravity is the nonconservation of the energy-momentum tensor…

• Rastall cosmology and the Λ CDM model2012 · аннотациясвернуть

  Rastall's theory is based on the nonconservation of the energy-momentum tensor. We show that, in this theory, if we introduce a two-fluid model, one component representing vacuum energy whereas the other pressureless…

• Bulk viscous cosmology2007 · аннотациясвернуть

  We propose a scenario in which the dark components of the Universe are manifestations of a single bulk viscous fluid. Using dynamical system methods, a qualitative study of the homogeneous, isotropic background scenario…
