论文摘要
我们考虑了Spin-2场的非线性有效作用，其“脱钩”极限在D维最大对称时空中提供了Fierz-Pauli的作用。我们发现，特别是对部分无质量领域的有效作用可以采取简洁的几何形式。还研究了使用有效动作在模型中背景度量的时间演变的确切解决方案。
We consider nonlinear effective actions for a spin-2 field, whose `decoupling' limit gives Fierz-Pauli action in D dimensional maximally symmetric spacetime. We find, especially, the effective action for a partially massless field can take a concise geometrical form. The exact solution for time evolution of the background metric in the model using the effective action is also studied.
