Minimal solutions of tropical linear differential systems
Dima Grigoriev, Cristhian Garay López
We introduce and study minimal (with respect to inclusion) solutions of systems of tropical linear differential equations. We describe the set of all minimal solutions for a single…

Matroids and semirings attached to toric singularity arrangements
Ethan Cotterill, Cristhian Garay López
Curve singularities are classical objects of study in algebraic geometry. The key player in their combinatorial structure is the {\it value semigroup}, or its compactification, the…

Real inflection points of real linear series on an elliptic curve
Ethan Cotterill, Cristhian Garay López
Given a real elliptic curve with non-empty real part and $[D]\in \mbox{Pic}^2 E$ its , we study the real inflection points of distinguished subseries of the complete rea…
