Outlier detection through Christoffel functions

We discuss how recent results on asymptotics for the Christoffel kernel built with orthogonal polynomials of one or several complex variables can help to detect outliers in a cloud of points.
Joint work with Mihai Putinar (University of California at Santa Barbara), Edward B. Saff (Vanderbilt University) and Nikos Stylianopoulos (University of Cyprus).
