The Logarithmic A-Discriminant
Madeleine Goertz, Bernd Sturmfels, Simon Telen
We extend the GKZ theory of discriminants to the setting of Euler integrals where both coefficients and exponents are variables. The integrand is the likelihood function of a toric…
Positive Geometries from Cubic Surfaces
Bernd Sturmfels, Simon Telen
We present a study of cubic surfaces from the novel perspective of positive geometry. Our positive geometries have dimension two (the surface minus its 27 lines), dimension three (…
The Algebraic Boundary of Graph Elliptopes
Monique Laurent, Francesco Maria Mascarin, Simon Telen
This paper studies the algebraic boundary of the elliptope of a graph . In particular, we completely characterize the algebraic boundary of whe…
Principal Matroid Determinants
Saiei-Jaeyeong Matsubara-Heo, Simon Telen
We develop a theory of principal determinants and hypergeometric systems for realizable matroids. Our framework parallels the toric theory of Gel'fand, Kapranov, and Zelevinsky (GK…
