2 Modified Einstein equations with the Jacobson’s approach
3 Quantum gravitational corrections to the Schwarzschild metric
3 Quantum gravitational corrections to the Schwarzschild metric
In order to solve (2.9), we start with the Ansatz
where
The Ricci scalar has the structure
Case I
We compare our solutions with the ones of Xiao and Tian [32], which read
With all these terms the final expression for the metric is
which generalizes the result of [32]. Notice that the coefficients (3.14) are formally divergent, but the solutions (3.15)-(3.17) are finite.
Case II
We compare now our solutions with the ones of Calmet and Kuipers, [22], which read
With all these terms the final expression for the metric is
hich generalizes the result of [22]. Again, notice that the coefficients (3.23) are formally divergent, but the solutions (3.24)-(3.26) are finite.
