在这项工作中，我们研究了部分约束的vielbein制定的新的quasiquillon理论的质量引力，quasiquillon场耦合到物理和基准度规，同时通过一个复合有效的度量和洛伦兹破坏引入的约束vielbein。这种形式主义改进了新的准双光子模型，因为Boulware-Deser鬼在所有尺度下都被完全非线性地去除。这在宇宙学的应用中也产生了至关重要的影响。我们导出了宇宙学背景演化的支配，并研究了吸引子解的稳定性。
In this work we study the partially constrained vielbein formulation of the new quasidilaton theory of massive gravity, where the quasidilaton field couples to both physical and fiducial metrics simultaneously via a composite effective metric and Lorentz violation is introduced by a constraint on the vielbein. This formalism improves the new quasidilaton model since the Boulware-Deser ghost is removed fully non-linearly at all scales. This also yields crucial implications in the cosmological applications. We derive the governing cosmological background evolution and study the stability of the attractor solution.
