在这篇短文中,我们讨论了超引力理论中费耶特-伊利奥普洛斯参数的量子化。我们认为,在超引力中,费耶特-伊利奥普洛斯参数决定了一个电梯的群作用的线丛,这样的电梯是量子化的。正如在刚性$mathcal{N}=1$超对称的D-条款解释的矩映射和辛约化,我们认为,在超引力的量子化的Fayet-Iliopoulos参数有一个自然的理解,在几何不变理论的线性化,代数几何版本的辛导数。
In this short article we discuss quantization of the Fayet-Iliopoulos parameter in supergravity theories. We argue that, in supergravity, the Fayet-Iliopoulos parameter determines a lift of the group action to a line bundle, and such lifts are quantized. Just as D-terms in rigid $mathcal{N}=1$ supersymmetry are interpreted in terms of moment maps and symplectic reductions, we argue that in supergravity the quantization of the Fayet-Iliopoulos parameter has a natural understanding in terms of linearizations in geometric invariant theory quotients, the algebro-geometric version of symplectic quotients.
