J. Jezierski, STABILITY OF REISSNER-NORDSTROM SOLUTION WITH RESPECT TO SMALL PERTURBATIONS OF INITIAL DATA, Classical and quantum gravity, 11(4), 1994, pp. 1055-1068
A new description of unconstrained degrees of freedom for the gravitat
ional field has been introduced. It has been applied to the descriptio
n of perturbed (nonlinear) initial data from the Reissner-Nordstrom so
lution.
