| الوصف: | We discuss the Bekenstein generalized entropy of Schwarzschild black hole, with the contribution of an external matter field affected by degrees of freedom inside the event horizon. To take into accountthis effect to the generalized entropy, we use Euclidean functional methods. In the Euclidean section of the Schwarzschild manifold, we consider an Euclidean quantum effective model, a scalar theory in the presence of an additive quenched disorder. The average the Gibbs free energy over the ensemble of possible configurations of the disorder is obtained by the distributional zeta-function method. In the series representation for the average free energy with respective effective actions emerges the generalized Schr\"{o}dinger operators on Riemannian manifolds. Finally, is presented the generalized entropy density with the contributions of the black hole geometric entropy and the external matter fields affected by the internal degrees of freedom. The validity of the generalized second law using Euclidean functional methods is obtained. Comment: 12 pages, 2 figures |
