HAWKING RADIATION FOR TWISTED COMPLEX SCALAR FIELDS ON THE REISSNER-NORDSTROM BLACK-HOLES AND DIRAC MONOPOLES

We study, both analytically and numerically, the contribution of the t wisted topologically inequivalent configurations (TICs) of complex sca lar fields on the Reissner-Nordstrom black holes to the Hawking radiat ion. Physically this contribution is conditioned by the natural presen ce of the Dirac monopoles on the black holes. When neglecting the own (external) electric field of black hole it is established that while i ncreasing the black hole electric charge Q to the extremal value Q=M ( M is the black hole mass), the given contribution to the total luminos ity (summed up over all the TICs) of the black hole decreases (from th e one of order 17% at Q=0) up to 0. At this value the total luminosity itself tends to 0.
