Construction of a complex null tetrad
text:
Calculations in the Newman–Penrose (NP) formalism of general relativity normally begin with the construction of a complex null tetrad { l a , n a , m a , m ¯ a } , where { l a , n a } is a pair of real null vectors and { m a , m ¯ a } is a pair of complex null vectors. These tetrad vectors respect the following normalization and metric conditions assuming the spacetime signature : l a l a = n a n a = m a m a = m ¯ a m ¯ a = 0 ; l a m a = l a m ¯ a = n a m a = n a m ¯ a = 0 ; l a n a = l a n a =
