研究了（1/16）-BPS AdS 5黑洞近视界几何中的巨和对偶巨型BPS组态.通过量子化解的空间，我们计算了对偶巨组态，并与黑洞熵进行了比较。这表明缺少简并因子，我们认为它来自角动量量子数。从D-膜世界体积来看，这是由BPS电磁波引起的。我们研究这些波的背景下，巨人和双巨人在黑洞近视界几何。我们进一步证明，打开波上的世界卷（1/8）-BPS双巨人在AdS 5？S5导致具有额外角动量量子数的（1/16）-BPS态。
We investigate giant and dual giant type BPS configurations in the near-horizon geometry of a certain (1/16)-BPS AdS5 black hole. By quantising the space of solutions we count the dual giant configurations and compare with the black hole entropy. This suggests a missing degeneracy factor which we argue comes from an angular momentum quantum number. From the D-brane world volume this arises from BPS electromagnetic waves. We study these waves in the context of giants and dual giants in the black hole near-horizon geometry. We further demonstrate that turning on waves on the world-volume of (1/8)-BPS dual giants in AdS5 ? S5 leads to (1/16)-BPS states with an additional angular momentum quantum number.
