论文摘要
我们通过采用Weyl补偿器形式主义来构建一种静脉引力的Weyl横向差异不变理论。低能动力学具有单个自旋两次重量，而没有标量的自由度。通过构造，它等同于非线性级别的单型重力（以及爱因斯坦的一般相对论）。结合我们早期构建Weyl横向差异不变的对称触发性重力理论，单型重力以三种替代方式表示。
We construct a Weyl transverse diffeomorphism invariant theory of teleparallel gravity by employing the Weyl compensator formalism. The low-energy dynamics has a single spin two gravition without a scalar degree of freedom. By construction, it is equivalent to unimodular gravity (as well as Einstein's general relativity with an adjustable cosmological constant) at the non-linear level. Combined with our earlier construction of a Weyl transverse diffeomorphism invariant theory of symmetric teleparallel gravity, unimodular gravity is represented in three alternative ways.
