Diffeomorphisms and boundary conditions I posted that on math.stackexchange because I hadn't find an answer here... |

Help with the understanding of boundary conditions on $AdS_3$ Related question, but I cannot seem to check if it's the correct way of solving this :\ |

Dark energy before radiation or after? Care to give some good links? |

Dark energy before radiation or after? So basically the inflation is due to dark energy? And therefore dark energy was there before the radiation era? |

Covariant derivative with upper index Hmm, but what if I have $D_\mu h^{\sigma\nu}$, and I need to lower the indices of the $h^{\sigma\nu}$, does that mean, that I can put the g's that will lower the indices of h outside also? |

Covariant derivative with upper index Thanks for the clarification, I'll try to make sth out of this expression :D |

Covariant derivative with upper index "Typically, it also implies that any derivatives appearing are with respect to covariant components instead of contravariant." What if I have mixed terms inside? I mean, in the expression I also have scalars, covariant vectors, contravariant vectors, covariant and contravariant tensors... |
