Abstract
In the extremal n-variable L-moment problem, the solution (=the
characteristic function of {p < 0},) p a polynomial, is determined by
finitely many moments, in a set A.
In [23], for quadrature domains (n = 2), the reduction of all moments
to the moments in A is implicit in the reconstruction of p using hyponor-
mal operators.
For n 2, assuming that the complexified of p has only isolated critical
points for its singularities, we show that the local algorithm [22] which
reduces to the moments in a base extends to the global case, with equality
