Bulk viscous matter interacting with decaying vacuum energy density: a model for late-time evolution of the Universe
Abstract The late-time cosmological expansion within a flat Friedmann–Lemaître–Robertson–Walker (FLRW) spacetime is studied using a model characterized by bulk viscous dark matter (bulk viscosity $$\zeta = \zeta _0 \rho _m H^{-1}+\zeta _1 H $$ ζ = ζ 0 ρ m H - 1 + ζ 1 H , $$\zeta _0$$ ζ 0 & $$\ze...
