dc.descriptionInequalities are derived for Wilson loops generalizing the well-known Bachas inequality for rectangular contours. The inequalities are compatible with the area law for large contours. The Polyakov cusp anomalous dimension of Wilson lines (playing an important role in QCD applications to hard processes) has a convex angular dependence. This convexity is crucial for the consistency of the inequalities with renormalization. Some parallel properties can be found in the string theory. The Kac-Ray cusp term from the "shape of a drum" problem has the same angular convexity property and plays the role of the cusp anomalous dimension in the effective string model for Wilson loops studied by Luescher, Symanzik and Weisz (LSW). Using heuristic arguments based on the LSW model, one can find an interesting connection between the inequalities for Wilson loops and inequalities for determinants of two-dimensional Laplacians with Dirichlet boundary conditions on the closed contours associated with Wilson loops.
