Summary

It is shown that a regular black hole with stationary initial and final states cannot have an extreme final state if this state is to occur at a finite value of an affine parameter, assuming that this space-time admits a certain test Maxwell field.

Riassunto

Si dimostra che un buco nero regolare con stati iniziali e finali stazionari non può avere uno stato finale estremo se questo stato deve aver luogo per un valore finito di un parametro affine, supponendo che questo spazio-tempo ammetta un certo campo di prova di Maxwell.

Резюме

Показывается, что нормальнаь черная дыра со стационарными начальным и конечным состояниями не может иметь экстремальное конечное состояние, если это состояние имеет место при конечном значении аффинного параметра, предполагая, что рассматриваемое пространство-время допускает определенное проверочное максвелловское поле.
