论文摘要
$ f（q）$重力是对称远程等同于一般相对论的延伸。我们证明了对$ f（q）$重力的汉密尔顿分析，并固定了一致的量规条件。使用标准的Dirac-Bergmann算法，我们表明$ f（q）$重力具有8个物理自由度。该结果反映出$ f（q）$重力的差异对称性由于固定量的固定而被完全损坏。此外，就扰动而言，我们讨论了这些自由度的可能模式分解。
$f(Q)$ gravity is an extension of the symmetric teleparallel equivalent to general relativity. We demonstrate the Hamiltonian analysis of $f(Q)$ gravity with fixing the coincident gauge condition. Using the standard Dirac-Bergmann algorithm, we show that $f(Q)$ gravity has 8 physical degrees of freedom. This result reflects that the diffeomorphism symmetry of $f(Q)$ gravity is completely broken due to the gauge fixing. Moreover, in terms of the perturbations, we discuss the possible mode decomposition of these degrees of freedom.
