共形群的陪集空间构造。I.不间断相

Coset space construction for the conformal group. I. Unbroken phase

Ivan Kharuk

摘要:

在陪集空间构造中构造共形不变理论的技术得到了发展。它再现了所有后果的共形不变性和拉格朗日广为人知的共形场论。诱导表示的方法,其中起着关键作用的建设,允许揭示一个特殊的作用的“南武-戈德斯通领域”的特殊保形变换。也就是说,它们对坐标的依赖性是由对称性决定的。这导致了对拉格朗日量的可能形式的约束的出现,这确保了离散对称确实是理论的对称。

英文摘要:

The technique for constructing conformally invariant theories within the coset space construction is developed. It reproduces all consequences of the conformal invariance and Lagrangians of widely-known conformal field theories. The method of induced representations, which plays the key role in the construction, allows to reveal a special role of the "Nambu-Goldstone fields" for special conformal transformations. Namely, their dependence on the coordinates turns out to be fixed by the symmetries. This results in the appearance of the constraints on possible forms of Lagrangians, which ensure that discrete symmetries are indeed symmetries of the theory.
