2+1维伽利略共形代数的仿射扩张

Affine Extension of Galilean Conformal Algebra in 2+1 Dimensions

Ali Hosseiny, Shahin Rouhani

摘要:

本文证明了一类非相对论性代数,包括非中心扩张Schrodinger代数和Galilean共形代数(GCA),在2+1中有一个迄今未知的仿射扩张。这种扩展产生于二维复平面的共形对称性。我们认为,这种仿射形式可能是对称性,解释了松弛的一些经典现象对他们的临界点。这个仿射代数允许一个中心扩张,并且可以在块中实现。批量实现表明,这个代数可以通过观察AdS理论的渐近对称性来推导。这表明AdS/CFT对偶性可能在四维中呈现特殊形式。

英文摘要:

We show that a class of nonrelativistic algebras including non centrally-extended Schrodinger algebra and Galilean Conformal Algebra (GCA) has an affine extension in 2+1 hitherto unknown. This extension arises out of the conformal symmetries of the two dimensional complex plain. We suggest that this affine form may be the symmetry that explains the relaxation of some classical phenomena towards their critical point. This affine algebra admits a central extension and maybe realized in the bulk. The bulk realization suggests that this algebra may be derived by looking at the asymptotic symmetry of an AdS theory. This suggests that AdS/CFT duality may take on a special form in four dimensions.
