In this work we consider perturbations of homogeneous and hypersurface orthogonal cosmological backgrounds with local rotational symmetry (LRS). using a method based on the 1 + 1 + 2 covariant split of spacetime. The backgrounds. of LRS class II. https://www.lightemupsequences.com/deal-find-14K-Gold-plated-Lobster-Closure-Freshwater-Pearl-Bracelet-super-grab/
