Abstract

Abstract In a specific adiabatic perfect fluid, intrinsic entropy density perturbations are the source of a space-dependent cosmological constant responsible for local void inhomogeneity. Assuming an anisotropic Locally Rotationally Symmetric space time, using the 1+1+2 covariant approach and a Lemaître space time metric, we study the cosmological implication of such a scenario giving a proper solution to the Hubble constant tension and providing, locally, also an effective equation of state with w ≤ -1.
