Entropy of Reissner - Nordstrom black hole surrounded by quintessence
Abstract：Based the Klein - Gordon equation of scalar field, the entropy of Reissner - Nordstrom black hole with quintessence is calculated by using the thin - film model method. This method avoids some drawbacks in the original brick -wall method such as the little mass approximation and neglecting logarithm term. It is found that the entropy of the black hole is 1/4 of the sum of the areas of the event horizon and cosmological horizon. So, the entropy of the system not only includes the contribution of the black hole horizon, but also includes the contribution of the cosmological horizon.
