In studying general relativity, many text deals with the derivation of schwarzschild metric starting from generic metric form. After that impose static, spherical symmetry and obtain the desired schwarzschild metric.
But i haven't find any reference for above process in kerr metric. (add a condition of rotation) In many textbooks on General relativity and black hole textbook they just state the form of kerr metric, and do some calculation.
Is there any reference (textbook or paper) contain explicit derivation of kerr metric?
