On the Uniqueness Problem for Quadrature Domains

26 Jan 2020 · Yacin Ameur, Martin Helmer, Felix Tellander ·

We study questions of existence and uniqueness of quadrature domains using computational tools from real algebraic geometry. These problems are transformed into questions about the number of solutions to an associated real semi-algebraic system, which is analyzed using the method of real comprehensive triangular decomposition.
