三维质量引力的约束结构

Constraint structure of the three dimensional massive gravity

M. Sadegh, A. Shirzad

摘要:

在Palatini形式下,研究了三维质量引力,即所谓的新质量引力的约束分析。我们证明了在度规的6个分量中,有2个分量是动态的,这与线性化理论(Fierz-Pauli理论)中存在一个矢量质量引力子是一致的。

英文摘要:

Constraint analysis of the three-dimensional massive gravity, the so- called new massive gravity, is studied in the Palatini formalism. We show that amongst 6 components of the metric, 2 are dynamical, which is compatible with the existence of one vector massive graviton in the linearized theory (Fierz-Pauli theory).
