摘要

建立了曲率和保形曲率动力学的张量、旋量和螺旋形式。给出了该形式下的线性化重力方程。从曲率动力学的角度研究了线性化重力中的重力辐射。证明了线性化重力中重力能Białynicki-Birula公式与Landau-Lifschitz公式的等价性。对于线性化重力的动量，也得到了类似的结果。

Curvature and conformal curvature dynamics formalisms and their applications in linearized gravity

Tensorial, spinorial and helicity formalisms of the curvature and conformal curvature dynamics are developed. Equations of linearized gravity within that formalisms are given. Gravitational radiation in linearized gravity in terms of curvature dynamics is investigated. Equivalence of the Białynicki-Birula formula for the gravitational energy in linearized gravity and the Landau–Lifschitz formula is proved. Analogous result is found for the momentum in linearized gravity.
