论文摘要
在这篇综述中，我们考虑了二次公制仪表重力拉格朗日，其中包含所有代数不变式，直至扭转，非质量和曲率中的二次阶。目的是为该理论收集已知的精确解决方案，以描述引力波和某些有用特性的传播。我们专注于与Levi-civita One不同的解决方案，并提供已经已知的轴向扭转溶液扩展到更通用的Lagrangians。最后，我们将简要讨论碰撞的波浪和Riemannian解决方案。
In this review we consider the quadratic Metric-Affine Gauge gravity Lagrangian, which contains all the algebraic invariants up to quadratic order in torsion, nonmetricity and curvature. The goal will be to collect the known exact solutions for this theory that describe the propagation of a gravitational wave and some useful properties. We concentrate on solutions whose connections are different from the Levi-Civita one and provide also the extension of already known axial torsion solutions to more general Lagrangians. At the end, we will briefly discuss colliding waves and Riemannian solutions.
