Abstract
Even dimensional defects and boundaries in conformal field theory support type anomalies on their world-volume. We show that the one-point functions of marginal operators, in the presence of defects and boundaries, are anomalous, and that the Wess-Zumino consistency condition relates them to the derivative of the -anomaly with respect to the marginal coupling. We also argue that the constant term for odd dimensional surfaces can depend on marginal parameters.
