• Christoffel function
• The polynomial inverse image method
• Jordan curves

In this work we apply the polynomial inverse image method to derive the limit behavior of LP Christoffel functions on the basis of the results obtained by Levin, Lubinsky, and Totik. We consider two situations: measures supported on the real line and measures supported on systems of Jordan curves.
