Positive del Pezzo Geometry
Nick Early, Alheydis Geiger, Marta Panizzut +2
Real, complex, and tropical algebraic geometry join forces in a new branch of mathematical physics called positive geometry. We develop the positive geometry of del Pezzo surfaces…
The Self-Projecting Grassmannian
Alheydis Geiger, Francesca Zaffalon
We introduce the self-projecting Grassmannian, an irreducible subvariety of the Grassmannian parametrizing linear subspaces that satisfy a generalized self-duality condition. We st…
Real Tropical Quartics and their Bitangents: Counting with Patchworking
Alheydis Geiger
For certain tropical quartic curves the existing techniques could not predict the lifting behavior of their bitangents over the real numbers. We close this gap by using patchworkin…
Graph Curve Matroids
Alheydis Geiger, Kevin Kuehn, Raluca Vlad
We introduce a new class of matroids, called graph curve matroids. A graph curve matroid is associated to a graph and defined on the vertices of the graph as a ground set. We prove…
