我们使用Noether电荷方法研究了高斯-博内和洛夫洛克引力下黑洞的熵，其中熵被给出为视界上合适的（n - 2）形式电荷的积分。我们将结果与其他方法得到的结果进行比较。我们还评论了在某些情况下出现的负熵，并表明在熵的定义中存在可适当选择的模糊性，以避免这个问题。
We investigate the entropy of black holes in Gauss-Bonnet and Lovelock gravity using the Noether charge approach, in which the entropy is given as the integral of a suitable (n - 2) form charge over the event horizon. We compare the results to those obtained in other approaches. We also comment on the appearance of negative entropies in some cases, and show that there is an additive ambiguity in the definition of the entropy which can be appropriately chosen to avoid this problem.
