论文摘要
在现场重新定义下，霍金 - 普通定理不是协变量的。如果这种转变下的不变性本质上是一个真正的原则，那么时空的奇异性就会成为可疑的物体。我们在这里回顾了协变量奇点的概念，即在时空差异和现场重新定义下不变的奇异性。
The Hawking-Penrose theorem is not covariant under field redefinitions. Should the invariance under such transformations be a true principle in Nature, spacetime singularities become dubious objects. We here review the concept of covariant singularities, that is, singularities that are invariant under both spacetime diffeomorphisms and field redefinitions.
