标题： Hamiltonian analysis for perturbative $λR$ gravity

摘要： 对在闵可夫斯基背景附近的线性化$\lambda R$引力进行哈密顿分析。 对于任意值的$\lambda$，给出了第一类和第二类约束，并报告了两个物理自由度。 此外，我们消去了第二类约束，并构造了广义狄拉克括号；然后，展示了广义相对论与$\lambda R$理论之间的等价性。 显示英文摘要

摘要： The Hamiltonian analysis for the linearized $\lambda R$ gravity around the Minkowski background is performed. The first-class and second-class constraints for arbitrary values of $\lambda$ are presented, and two physical degrees of freedom are reported. In addition, we remove the second-class constraints, and the generalized Dirac brackets are constructed; then, the equivalence between General Relativity and the $\lambda R$ theory is shown.
