On the energy of a charged dilaton black hole

摘要

Employing the energy-momentum pseudotensor of Einstein, we obtain the energy distribution of a dyonic dilaton black hole. The energy distribution of this black hole depends on mass M, electric charge Q(e), magnetic charge Q(m) and the asymptotic value of the dilaton phi(0). We also make some comparisons between the results of Virbhadra et. al. and ours.
