摘要：
The non-trivial ultraviolet fixed point in quantum gravity is calculated by means of the exact renormalization group equation in d-dimensions (2 similar or equal to d less than or equal to 4). It is shown that the ultraviolet non-Gaussian fixed point which is expected from the perturbativelly E-expanded calculations in 2 + epsilon gravity theory remains in d = 4. Hence it is possible that quantum gravity is an asymptotically safe theory and renormalizable in 2 < d.
