膜、箭图和波函数

Branes, quivers and wave-functions

Taro Kimura, Miłosz Panfil, Yuji Sugimoto, Piotr Sułkowski

摘要:

我们考虑一个大类的膜复曲面带几何,非周期和周期的。对于一个固定的背景几何,我们表明,这种膜的配分函数可以被重新解释,一方面,作为一个生成级数,另一方面,作为波函数在各种偏振。我们确定操作的箭图,以及$SL(2,\mathbb{Z})$变换,这对应于这些膜的位置变化。我们的结果证明了与这类膜相关的BPS多重性的完整性,揭示了它们如何在极化的变化下进行变换,并暗示了膜振幅的所有其他性质,这些性质是从与颤动的关系中得出的。

英文摘要:

We consider a large class of branes in toric strip geometries, both non-periodic and periodic ones. For a fixed background geometry we show that partition functions for such branes can be reinterpreted, on one hand, as quiver generating series, and on the other hand as wave-functions in various polarizations. We determine operations on quivers, as well as $SL(2,\mathbb{Z})$ transformations, which correspond to changing positions of these branes. Our results prove integrality of BPS multiplicities associated to this class of branes, reveal how they transform under changes of polarization, and imply all other properties of brane amplitudes that follow from the relation to quivers.
