论文摘要
在本文中,我们研究了纽曼 - 芬罗斯形式主义中的自动重力。我们从Newman-Unti解决方案中指定了自动偶联解决方案空间。我们表明,自二重力的渐近对称性仍然是(扩展的)BMS对称性。我们以分析形式将自动二型taub-nut溶液转换为纽曼 - unti仪。
In this paper, we study self-dual gravity in the Newman-Penrose formalism. We specify the self-dual solution space from the Newman-Unti solutions. We show that the asymptotic symmetries of the self-dual gravity are still the (extended) BMS symmetries. We transform the self-dual Taub-NUT solution into the Newman-Unti gauge in analytical form.
