Ezra Newman and his colleagues found a particular solution to Einstein’s field equations of general relativity in 1965. This is now known as the Kerr-Newman solution for a charged rotating black holes and as the most general solution, consequently of the no-hair theorem, which characterizes black holes uniquely by mass, electric charge, and angular momentum. If the electric charge is zero then the solution is just known as Kerr solution, found by Roy Kerr in 1963. If the electric charge is not zero while the rotation is zero then it is known as Reissner-Nordstrom solution. If both are zero then it is known as Schwarzschild solution. Time independence: [∂E(g)]˛=[∂F(a)×∂r(a)]·[∂F(b)×∂r(b)] and Mass independence: ¶a(t)·¶r(t)=c˛ |
