论文摘要
我们报告了一个新的单参数对称性，不均匀和时间依赖的溶液，真空brans-dicke场方程与爱因斯坦重力的Roberts标量场几何形状一致。新的解决方案是球形的，并且依赖时间，并且包含裸中心的奇异性。我们将其用作种子，使用已知的真空brans-dicke Gravity的对称性产生另一个两参数溶液家族。
We report a new one-parameter family of spherically symmetric, inhomogeneous, and time-dependent solutions of the vacuum Brans-Dicke field equations which are conformal to the Roberts scalar field geometries of Einstein gravity. The new solution is spherical and time-dependent and contains a naked central singularity. We use it as a seed to generate another two-parameter family of solutions using a known symmetry of vacuum Brans-Dicke gravity.
