f-符号、Killing张量和守恒Bel型流

f-symbols, Killing tensors and conserved Bel-type currents

Ovidiu Tintareanu-Mircea

摘要:

在广义相对论的框架下,我们证明了由Killing向量场的三种推广,即f-符号、对称Stäckel-Killing张量和反对称Killing-Yano张量,在Einstein空间中,通过对它们进行适当的压缩,可以得到具有Bel或Bel-Robinson张量性质的四阶张量的守恒流.

英文摘要:

In the framework of the General Relativity we show that from three generalizations of Killing vector fields, namely f-symbols, symmetric Stäckel-Killing and antisymmetric Killing-Yano tensors, some conserved currents can be obtained through adequate contractions of the above mentioned objects with rank four tensors having the properties of Bel or Bel-Robinson tensors in Einstein spaces.
