f-symbols, Killing tensors and conserved Bel-type currents
arXiv:1012.5368 · doi:10.1142/S0217732311034888
Abstract
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.
