Poynting vector, super-Poynting vector, and principal observers in electromagnetism and general relativity [PDF]
Classical and Quantum Gravity, 2021 Abstract In electromagnetism, the concept of Poynting vector as measured by an observer is well known. A mathematical analogue in general relativity is the super-Poynting vector of the Weyl tensor. Observers for which the (super-)Poynting vector vanishes are called principal
