Please recommend a physics problems book similar to Demidovich If you solve Irodov, you'll probably be able to solve anything else in the 'general physics' sense ;) So I agree with ramanujan_diracs choice :) |

Boundary conditions for fields in Kerr/CFT I found this paper: arxiv.org/abs/0908.0184v3, and there are lots of boundary conditions there. But I am interested into how he calculated the 4.10 formula? I have the metric (therefore all the coefficients are known), he even gives the generators of the asymptotic symmetry in equation 4.5, but I cannot reproduce the result he got :\ I used the formula $(\mathcal{L}_\xi g_{\mu\nu})^\sigma=g_{\mu\nu,\sigma}\xi^\sigma+g_{\sigma\nu}\xi^\sigma_{,\mu}+g_{\mu\sigma}\xi^\sigma_{,\nu}$, and I tried going by componenets but I don't get the same result (so I must be doing something wrong :) |

Boundary conditions for fields in Kerr/CFT Well from what I've read, if the Lie derivative of metric tensor along some vector field is zero, then that field represents a generator of an isometry group. The boundary condition is given as a matrix of some kind of subleading terms of the deviation of the metric from the background metric. And there are two boundaries (r=$\infty$ and r=$-\infty$)... I found one paper that has some more computation, but I'm not sure how they got the $\mathcal{L}_\xi g_{\mu\nu}$ :\ |

Uncertainty writing Thank you! I wasn't really sure if I'm interpreting it right :) I'll accept your answer in 2 minutes, since I cannot do that atm xD |

Visualization of de Sitter spaces Thank you for the explanation, I had some troubles with this. I am going to look at the pdf you provided :) |

What is the significance of action? Plus, the term T-V, is just the classical Lagrangian, and if you know that, using just what Alec S said, you can obtain the equations of motion for the given system :) |

How do you find spin of a particle from experimental data? Great! Thanks ^^ |
