Query: On anomalous conformal Ward identities for Wilson loops on polygon-like
  contours with circular edges   We derive the anomalous conformal Ward identities for ${\cal N}=4$ SYM Wilson
loops on polygon-like contours with edges formed by circular arcs. With a
suitable choice of parameterisation they are very similarly to those for local
correlation functions. Their solutions have a conformally covariant factor
depending on the distances of the corners times a conformally invariant
remainder factor depending, besides on cross ratios of the corners, on the cusp
angles and angles parameterising the torsion of the contours.
