Abstract
We study a finite, divergence free approach to renormalisation originally proposed in the early '70s by Blaer and Young, and Callan. It is based on equations similar to the Callan-Symanzik equations, and introduced in the context of theory. We generalise this method to the case of two interacting scalar fields, with obvious generalisation to an arbitrary number of fields.
