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.
