A short note on Cayley-Salmon equations

Marvin Anas Hahn, Sara Lamboglia, Alejandro Vargas

A Cayley-Salmon equation for a smooth cubic surface $S$ in $P^{3}$ is an expression of the form $l_{1} l_{2} l_{3} - m_{1} m_{2} m_{3} = 0$ such that the zero set is $S$ and $l_{i}$ , $m_{j}$ are…

Tropical convex hulls of polyhedral sets

Cvetelina Hill, Sara Lamboglia, Faye Pasley Simon

In this paper we focus on the tropical convex hull of convex sets and polyhedral complexes. We give a vertex description of the tropical convex hull of a line segment and a ray. %i…

Tropical Fano Schemes

Sara Lamboglia

We define a tropical version $\F_d(\trop X)$ of the Fano Scheme $\F_d(X)$ of a projective variety $X \subseteq P^{n}$ and prove that $\F_d(\trop X)$ is the support of a polyhe…
