One ERROR correction in Cristoffel symbols of second kind.

> you described, but I put below Christoffel symbols of second

> f = 1 - a / r
>
> K^t_tr = K^t_rt = a / (2r^2 f)
>
> K^r_tt = ac^2 / (2r^2),

> K^r_rr = -a / (2r^2 f),
>
> K^r_TT = -r f,   (T=Theta),
>
> K^r_PP = - r f sin^T,  (P=Phi),

ERROR CORRECTION: above line should be as:

K^r_PP = - r f sin^2 T,  (P=Phi),

>
> K^T_rT = K^T_Tr = 1 / r,
>
> K^T_PP = -sinT cosT,
>
> K^P_rP = K^P_Pr = 1 / r,
>
> K^P_TP = K^P_P_T = cotT
