Higher genus Siegel forms and multi-center black holes in N=4 supersymmetric string theory

Frederik Denef, Shamit Kachru, Zimo Sun, Arnav Tripathy

摘要:

我们猜想,三次Siegel形式$1/\sqrt{χ_{18}}$的傅里叶系数计算了在$K3 \times T^2$上紧化的II型弦论中三中心BPS束缚态的简并度。我们提供的证据,我们的猜想的形式与物理考虑的一致性的墙壁穿越,全息边界,并出现合适的计数功能(涉及逆的模块判别$Δ$和逆的Igusa尖形$Φ_{10}$)在限制计数退化到涉及单中心或两个中心的对象。

英文摘要:

We conjecture that the Fourier coefficients of a degree three Siegel form, $1/\sqrt{χ_{18}}$, count the degeneracy of three-center BPS bound states in type II string theory compactified on $K3 \times T^2$. We provide evidence for our conjecture in the form of consistency with physical considerations of wall-crossing, holographic bounds, and the appearance of suitable counting functions (involving the inverse of the modular discriminant $Δ$ and the inverse of the Igusa cusp form $Φ_{10}$) in limits where the count degenerates to involve single-center or two-center objects.
