Abstract:

The quantum corrections to the entropy of the Barriola Vilenkin black  hole due to the gravitation electromagnetic and neutrino fields are calculated b y using the  brick wall model. It is shown that the quantum corrects consist in two parts :  One is aquadratic divergent term at event horizon and is proportional to t he s urface area of the event horizon. The other is two logarithmically divergent terms which not only depend on the characteristics of the black hole but also on th e spin of fields. The whole expression does not take the form of the scalar field.
