摘要:

我们讨论了由于纯引力Chern-Simons项引起的黑洞熵公式的拓扑和整体规范性质。我们研究在什么样的拓扑和几何条件下,这个公式是定义良好的。为此,我们必须分析Chern-Simons项本身的整体性质及其耦合的量子化。我们表明,在某些情况下,耦合量子化可能干扰的熵公式的良好的确定性。

英文摘要:

We discuss the topological and global gauge properties of the formula for a black hole entropy due to a purely gravitational Chern-Simons term. We study under what topological and geometrical conditions this formula is well-defined. To this end we have to analyze the global properties of the Chern-Simons term itself and the quantization of its coupling. We show that in some cases the coupling quantization may interfere with the well-definiteness of the entropy formula.
