Abstract

The ultralocal limit along timelike geodesics, in which any geometry reduces to Bianchi I, does not extend to non-geodesic timelike observers. Exceptions are discussed, including particles with variable mass, test particles in Einstein frame scalar-tensor gravity, and self-interacting dark matter.

非测地线类时观测者与超局域极限

在类时测地线上的超局部极限中，任何几何都简化为比安奇I，但它不能扩展到非测地线类时观察者。讨论了例外情况，包括变质量粒子、爱因斯坦坐标系标量张量引力中的测试粒子和自相互作用暗物质。
