Abstract
We introduce an approach for calculating the quantum loop corrections in the phi(4) theory. Differential regularization and background-field method are essential tools and are used to calculate the effective ac tion of the theory to two-loop order. Our approach is considerably sim pler than other known methods and can be readily extended to higher-lo op calculations and to other models.
