摘要
It is shown that Schwarzschild black hole and de Sitter solutions exist as exact solutions of a recently proposed relativistic covariant formulation of (power-counting) renormalizable gravity with a fluid. The formulation without a fluid is presented here too. The stability of the solutions is studied and their corresponding entropies are computed by using the covariantWald method. The area law is shown to hold both for the Schwarzschild and for the de Sitter solutions found, confirming that, for the beta = 1 case, one is dealing with a minimal modification of general relativity.
