Quantum entropy of the Vaidya-Bonner-de Sitter black hole arising from gravitati onal fields

Abstract

The quantum corrections to the entropy of the Vaidya-Bonner-de Sitter black hole due to gravitational fields are investigated by using the brick-wall model.When the event horizon of the black hole does not depend upon the advanced-time,the results coincide with that of the Reissner-Nordstrm-de Sitter black hole.
