Constrained -approximation by polynomials on subsets of the circle
L Baratchart, Juliette Leblond, Fabien Seyfert
We study best approximation to a given function, in the least square sense on a subset of the unit circle, by polynomials of given degree which are pointwise bounded on the complem…

Constrained extremal problems in the Hardy space H2 and Carleman's formulas
Laurent Baratchart, Juliette Leblond, Fabien Seyfert
We study some approximation problems on a strict subset of the circle by analytic functions of the Hardy space H2 of the unit disk (in C), whose modulus satisfy a pointwise constra…
