摘要：
Polyakov's two-dimensional quantum gravity is analysed in the perturbative approach. The two-dimensional general invariance of the effective action is preserved using the background-field method. Renormalization of the gravitational coupling and redefinition of the graviton field are performed explicitly at the one-loop order. Some interesting aspects (renormalizability, gauge condition, renormalization and β-function of the gravitational coupling, redefinition of the graviton field) are found. © 1990.
