摘要
Quantum corrections to the entropy of a static, spherically symmetric black hole-global monopole system arising from the Dirac spinor field are investigated by using the brick wall method. It is shown that if we ignore the usual contribution from the vacuum surrounding the system, then the quantum corrections for the static black hole consist of two parts: One is a quadratically divergent term which takes a geometric character. The other is a logarithmically divergent term which is not proportional to the area of the horizon. The renormalization of the quadratic and logarithmic divergences is also investigated.
