引力子与微分算子复形

Gravitons and a complex of differential operators

Kirill Krasnov

摘要:

引力现在被理解为在壳层上变得简单。我们勾勒出它如何变得简单,也脱壳,当重新制定适当的。因此,我们描述了一个简单的拉格朗日引力子,利用一定复杂的微分算子。拉格朗日量的构造类似于麦克斯韦理论,只是使用了不同的复数。这个复形,以及我们对引力子的描述,在任何半共形平坦的四维流形上都是有意义的。

英文摘要:

Gravity is now understood to become simple on-shell. We sketch how it becomes simple also off-shell, when reformulated appropriately. Thus, we describe a simple Lagrangian for gravitons that makes use of a certain complex of differential operators. The Lagrangian is constructed analogously to that of Maxwell's theory, just using a different complex. The complex, and therefore also our description of gravitons, makes sense on any half-conformally flat four-dimensional manifold.
