英文摘要 | It has been shown [Chin. Phys. Lett. 25 (2008) 4199] that the generalized second law of thermodynamics holds in Einstein gravity. Here we extend this procedure for Gauss-Bonnet and Lovelock gravities. It is shown that by employing the general expression for temperature T(h) = |kappa|/2 pi = 1/2 pi(r) over tilde (A) (1 - (r) over tilde (A)/2H (r) over tilde (A)) associated with the apparent horizon of a Friedman-Robertson-Walker (FRW) universe and assuming T(m) = bT(h), we are able to construct conditions for which the generalized second law holds in Gauss-Bonnet and Lovelock gravities, where T(m) and T(h) are the temperatures of the source and the horizon respectively. |
