- Beschreibung
- The problem of finding homogeneous Einstein metrics on a compact homogeneous space reduces to solving a system of Laurent polynomial equations. This is an example of a vertically parametrized system; such systems arise in algebraic statistics and chemical reaction networks. We prove that the number of isolated solutions of this system is bounded above by the central Delannoy numbers and we describe the discriminant locus where the number of isolated solutions drops in terms of the principal A-determinant.
