Null conformal Killing-Yano tensors and Birkhoff theorem
Joan Josep Ferrando, Juan Antonio Sáez
We study the space-times admitting a null conformal Killing-Yano tensor whose divergence defines a Killing vector. We analyze the similitudes and differences with the recently stud…

Birkhoff theorem and conformal Killing-Yano tensors
Joan Josep Ferrando, Juan Antonio Sáez
We analyze the main geometric conditions imposed by the hypothesis of the Jebsen-Birkhoff theorem. We show that the result (existence of an additional Killing vector) does not nece…
