Abstract
The trace anomaly of conformal field theories in four dimensions is characterized by '' and ''-functions. The scaling properties of the effective action of a CFT in the presence of boundaries is shown to be determined by , and two new functions (charges) related to boundary effects. The boundary charges are computed for different theories and different boundary conditions. One of the boundary charges depends on the bulk charge.
