Existence of Reissner-Nordstrom type black holes in f(R) gravity

We investigate the existence of Reissner-Nordstr"om (RN) type black holes in f® gravity. Our emphasis is to derive, in the presence of electrostatic source, the necessary conditions which provide such static, spherically symmetric (SSS) black holes available in f® gravity. We also study the thermodynamics of the black hole solution.
