Weyl anomalies for conformal defects
A seminar in the Fields, Strings, and Geometry Group research seminar series.

In this talk, I will cover recent progress made toward characterizing and classifying extended objects (defects) in conformal field theories through anomalies. In particular, I will discuss the Weyl anomaly for two- and four-dimensional conformal defects, and I will show how defect Weyl anomaly coefficients can be computed using correlation functions and holographically. I will demonstrate the utility of these methods in computing some of the 29 defect Weyl anomaly coefficients for monodromy defects in six-dimensional free field theories and for AdS5 probe branes in AdSd+1.
