Entropy and Energy of Static Spherically Symmetric Black Hole in <i>f</i>(<i>R</i>) Theory

Abstract

We consider the new horizon first law in f ( R ) theory. We derive the general formulas to computed the entropy and energy for static spherically symmetric black hole. For applications, some nontrivial solutions in some popular f ( R ) theories are investigated, the entropies and the energies of static spherically symmetric black holes in these models are first calculated.
