Resumen:
Outside a black hole, perturbation fields die off in time as 1/tn. For spherical
holes n = 2 l + 3 where l is the multipole index. In the nonspherical Kerr
spacetime there is no coordinate-independent meaning of multipole, and a
common sense viewpoint is to set l to the lowest radiatiable index, although
theoretical studies have led to very different claims. Numerical results, to
date, have been controversial. Here we show that expansion for small Kerr
spin parameter a leads to very definite numerical results confirming previous
theoretical predictions./tn. For spherical
