Classical and Thermodynamic Stability of Black Branes

Scalar-vector-tensor decomposition - Wikipedia 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 (see Helmholtz decomposition.) general relativity - Traceless-transverse gauge vs In Hobson et al (2006) pg514 they write the formula for the flux in the traceless-transverse gauge: \newcommand{\p}{\frac{\partial #1}{\partial #2}} \newcommand The transverse traceless gauge and quadrupole sources A gravitational wave propagating in the +z direction is usually described by the transverse spatial components hxx, hyy, hxy in the transverse traceless gauge in which hxx+hyy=0.

* Lorenz gauge: A gauge in which ∇ a A a = 0, or = (any g-valued function on spacetime), so ∇ 2 A a = J a; The residual freedom is A a $$\mapsto$$ A a + ∂ a χ, with ∇ 2 χ = 0, and can be used to impose the Coulomb gauge; Note: It is named after Ludwig Valentin Lorenz, and not after the Hendrik Antoon Lorentz of the Lorentz The recent starting of the gravitational wave (GW) astronomy with the events GW150914, GW151226, GW170104, and the very recent GW170814 and GW170817 seems to be fundamental not only in order to obtain new intriguing astrophysical information from our surrounding Universe, but also in order to discriminate among Einstein’s general theory of relativity (GTR) and alternative gravitational XII, we found that the transverse-traceless gauge gravitational wave emitted from a source was hTT ij= 1 R 2Q¨ +n kn lQ¨ klδ +n in jn n Q¨ −2n n Q¨ik −2n n Q¨jk .
