Scalar–vector–tensor decomposition
text:
In cosmological perturbation theory, the scalar–vector–tensor decomposition is a decomposition of the most general linearized perturbations of the Friedmann–Lemaître–Robertson–Walker metric into components according to their transformations under spatial rotations. It was first discovered by E. M. Lifshitz in 1946. It follows from Helmholtz's Theorem The general metric perturbation has ten degrees of freedom. The decomposition states that the evolution equations for the most general linearized p
