马蒂厄月光和对称冲浪

Mathieu Moonshine and Symmetry Surfing

Matthias R. Gaberdiel, Christoph A. Keller, Hynek Paul

摘要:

Mathieu Moonshine,观察到K3上椭圆亏格的傅立叶系数可以解释为Mathieu群M24的表示的维数,已经被抽象地证明,但是缺少关于BPS态上Mathieu群的表示的概念理解。不久前,Taormina和Wendland利用“对称性冲浪”的思想表明,这种作用可以自然地定义在最低的非平凡BPS态上,即,通过结合不同的K3西格玛模型的对称性。在本文中,我们发现非平凡的证据表明,这种结构可以推广到所有的BPS状态。

英文摘要:

Mathieu Moonshine, the observation that the Fourier coefficients of the elliptic genus on K3 can be interpreted as dimensions of representations of the Mathieu group M24, has been proven abstractly, but a conceptual understanding in terms of a representation of the Mathieu group on the BPS states, is missing. Some time ago, Taormina and Wendland showed that such an action can be naturally defined on the lowest non-trivial BPS states, using the idea of `symmetry surfing', i.e., by combining the symmetries of different K3 sigma models. In this paper we find non-trivial evidence that this construction can be generalized to all BPS states.
