On the Christoffel Function for the Generalized Jacobi Measures on a Quasidisk

On the Christoffel Function for the Generalized Jacobi Measures on a Quasidisk

We establish the exact (up to the constants) double inequality for the Christoffel function for a measure supported on a Jordan domain bounded by a quasiconformal curve. We show that this quasiconformality of the boundary cannot be omitted.
