Quadrature domains
text:
In the branch of mathematics called potential theory, a quadrature domain in two dimensional real Euclidean space is a domain D together with
a finite subset {z1, …, zk} of D such that, for every function u harmonic and integrable over D with respect to area measure, the integral of u with respect to this measure is given by a "quadrature formula"; that is, where the cj are nonzero complex constants independent of u. The most obvious example is when D is a circular disk: here k = 1, z1 is the ce
