Popis: | Up to a constant factor, we compute the Christoffel function on planar domains with boundary consisting of finitely many C2 curves such that each corner point of the boundary has interior angle strictly between 0 and $$\pi $$ . The resulting formula uses the distances from the point of interest to the curves or certain parts of the curves defining the boundary of the domain. |
