Outlier detection through Christoffel functions

Bernhard Beckermann

University of Lille, France   -   bbecker@math.univ-lille1.fr

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).
