论文摘要
在这项工作中，我们研究了Berwald Type的Randers空间，并分析了该类别的Finsler Gravity的Pfeifer和Wohlfarth的真空场方程。我们表明，在这种情况下，场方程等于消失的Finsler ricci张量，类似于爱因斯坦重力。这意味着在这种情况下，所考虑的真空场方程和Rutz方程重合。我们还构建了berwald-randers类型的所有精确解针对真空鳍重力，结果原来是由ccnv（协变量恒定的null vector）洛伦兹时空组成的，通常称为pp波，是pp波，是由pp波波波动销售的1型。因此，我们将发现的解决方案称为Randers PP波。
In this work we study Randers spacetimes of Berwald type and analyze Pfeifer and Wohlfarth's vacuum field equation of Finsler gravity for this class. We show that in this case the field equation is equivalent to the vanishing of the Finsler Ricci tensor, analogously to Einstein gravity. This implies that the considered vacuum field equation and Rutz's equation coincide in this scenario. We also construct all exact solutions of Berwald-Randers type to vacuum Finsler gravity, which turn out to be composed of a CCNV (covariantly constant null vector) Lorentzian spacetime, commonly known as pp-wave, and a 1-form given by the pp-wave distinguished null vector. We therefore refer to the found solutions as Randers pp-waves.
